Polishing Aluminum Step Zero & One

There are many types of aluminum and some are harder to polish than others. Cast aluminum is one of the most difficult kinds of aluminum to polish, but it's one of the most beautiful when it's done right. In this video I take a 20+ year old used piece of cast aluminum that was purchased on eBay and first challenge its worthiness for this job. While this may seem like a spoiler in the description because the job continues beyond this point, please understand that this is not the first cylinder head that I put through these paces. This video demonstrates WHY you would want to have high standards for any part that receives this kind of treatment, as well as the most effective use of your time while starting this process.
A successful KZbin channel uploads at least twice a week. Videos about time-consuming, laborious processes are not profitable videos for me to make, but I understand how much satisfaction I receive from having done these kinds of jobs myself, and I want to share what I know about these jobs with all of you. I want all of you to experience that satisfaction from your efforts. My videos are typically time-consuming long-haul jobs that can not conform to Google's algorithm schedule. The kinds of videos I make CAN NOT follow that schedule, but I make these videos not for Google or their algorithms. Monetization might provide me with $60-$80 of ad revenue for it, while being subjected to ranked promotion and politicized filtering, but like I said... this is not for them, it's for you. I want this to be a resource for anyone who needs guidance and I want it to be available in your time of curiosity and need. If not for my supporters on Patreon who bridge this gap that the algorithms create for me, I would have wrapped up and quit my production years ago. Please understand that the names scrolling by at the end of my videos are the people who get this, who want me to keep making these kinds of videos, and who want YOU to have these kinds of videos. Everyone who has contributed or who continues to contribute to my production on Patreon page are the reasons why all of you have it. If you wish to support what I do here, you can do so at www.patreon.com/jafromobile. Every donation helps me help the willing, and I spend everything I make from it on doing this.
I open with the background of what inspired me to start doing this, who helped me the most once I attempted it for myself, and what I accomplished with my efforts. I believe these things are important qualifications to share because these techniques have been applied to automobiles for over 100 years (the "brass cars" of the 1900's-1910's) and repeated on many cars and motorcycles throughout the post-war era of hot rodding through today. It's an artisan's touch to engine building that does not improve the mechanical performance of an engine in any measurable way. To put it simply, it's for the fans. It's for attention. It's an aesthetic treatment. But for the one doing the work, the parts only receive this kind of treatment because that car is loved. It's a visual demonstration that it's their favorite thing. The maintenance it requires is why it's typically only seen on SHOW CARS, and why it's most often applied to high performance builds. That car owner has been receiving dividend payments of adrenaline and attention with it that made them fall in love with it. They do this because they want it to stand out among a crowd of others like it, but most importantly to make an impression on everyone who is a FAN of it. They want to make more fans of it, and people love shiny, unusual things. It's an extremely effective tactic as it makes people stop walking, and look at it. And keep looking at it. And then start looking FOR it.
Please consider how you're using these techniques and why they're beneficial to you if you wish to do this to your parts. I don't want to lose any friends over the punishment endured by anyone trying to accomplish this. If your car spends more time with the hood open than closed, then this might be for you... but it's a whole lot of work to maintain, and God forbid you break it like I did.
I have several MAJOR announcements in this series that extend beyond the polishing job and provide more context of my goals, so please come back and watch the rest. More coming soon, Stay Tubed!

@@richardprice5978 In short, on raw polished aluminum, YES. There are specialized clear coats out there that are for this very purpose/ application. VHT is one of the vendors that comes to mind. They produce a Urethane Clear for this and I have used it with good results like most of the stuff VHT makes it is good quality and works well as long as you follow the directions and the basic properties of painting. There is also the choice to use a good metal sealant like ZoopSeal. That stuff is excellent and I highly recommend using it on your raw polished aluminum to prevent it from hazing up, and to keep you from the constant maintenance and touch-ups that it entails when left untreated.👍👍🙂

This is typical Jafro doing his micro focused thing, one step broken down at a time. Some may get bored, but they won no trophies for their effort, lack of effort. Doing things by hand is often misunderstood and taken for granted by those that haven’t the first clue as to what this level of dedication requires. As a practitioner of this type of working ethic, I don’t think about it. You know what is required and you do each step and inspect and reevaluate it. It isn’t for many. Most don’t want to and fewer have the focus to endure and press on. I admire it because I am a practitioner and I get it. Lazy doesn’t even visit here. Rock your work and press on Jafro. Your work is awesome ass! Stay safe my mates!😊👍🏻😷

Good job. I’m a die maker. When I polished my bike engine I used radius gauges and made up some polishing bobs for the internal rads. Using various diamond pastes. In step 1. The obvious areas I was using jewellery tools diemakers files even a jewellers eye glass. And of course gauges. Then I put the fairing back on the bike and you could only see about %20 of what I’d done. Insanity and. Never again.

This is the video I've been looking for. I've got two Ducati 250 engines from the 1960's and want to do them justice. I'm 74 years old -- lifelong musician and have painted houses for decades. So I know enough about preparation to jump into this with eyes wide open. So thanks. One nice thing about labor intensive work like this is that there won't be many copy cats. If the process took three hours everyone would have gleaming aluminum work. Not going to happen in this age. Thanks again -- this will be my ongoing reference.

[@zackk695]

I was so impressed with this video and couldn’t quit watching it. I had to see every detail. I learned a lot as well. I did want to mention that none of the sanding needs to be done by hand. You can start with a dremel and 120 grit and get your flat surface. For all edges, corners and tight spaces I use a dremel wire wheel #447. It won’t leave noticeable scratch’s without using a magnifying glass. I use wire wheels on drills for the big areas and then maybe 240 grit sandpaper. From there I go to 400 grit then to 600 grit and I do wet sanding using a spray bottle. I then buff and polish. I like using the bars to buff it out which are usually black,maroon and then the polish is either white or green. It will make aluminum look chrome. Cleaning has always been the same and I just use a mild car was soap and water. As mentioned I do have to dry it. You should let the tools do the work for you and shave off about half the time. It will look like the head was dipped in chrome

[@SiNNeR90737]

@jafromobile... I feel for you. I also do metal polishing. I love the finished product, but the first few steps are horrific and tedious as all hell. I was taught by a guy who used to polish engines on Harley's for a few "HA's" and the direction of sanding is most important. Absolutely have to sand in the direction of the grain of the metal. There's so much time and involved and a very trained eye to turn something from a regular piece of metal and turn it into a mirror shine that is flawless. It is absolutely something that you have to be committed to. I also can't look at any unpolished metal without wanting to polish it even knowing the can of worms it opens. But i fell in love with it as soon as i finished my first project, which was a simple shotgun barrel and reciever. After that, I was addicted and have not stopped, and it's been 15 years since that shotgun. So, I am aware of what you go through. Im glad to see someone else is addicted to it.

[@gjrt7573]

Ive done this before, in my opinion; It was never terrible experience. It was more a fun bless to dedicate your personal skill to something. Everything Ive seen here, I have done. There ways to power through it I'll agree that no power tool can do the job. Doing it by hand is something the best and only choice. As for pitting or casting pores, which I would like to ask as what the difference to you since I thought that the factory would deem the part as a failed casting. The soft buffing bit does work gets though those letters you just have to sacrifice it. I would say my only limitation is selection in my area for tools and bits and things of that nature. For the pitting I just resurface that areas but it does lave a warped look. Doing it more often get rid of mistakes.

Intake manifolds are brutal. I quit one and painted it, myself. If you have to do it, polish what you can see on the outside. The back and bottom of it can't be seen at all. Just clean the rest.

The fattened budgets, quest for insanity and rampant modification in that community caused them to develop all kinds of ridiculous 600-700hp NA builds. It was like the Italian car that had no rules against modification. People have put big blocks in them, but you are correct... the 351-C is not a big block.

Spectacular work!

That sandpaper you using is for a palm sander. Walmart 3M is whatcha want ;)

[@evil_me]

I would never polish anything on my vehicles, I prefer paint in body color or accent color. That said I appreciate the effort people put into their own cars and always love the videos here.

[@nobodyimportant1983]

That exhaust manifold bro looks really great... Been watching you for a long time Tom's turbo garage was the first real DSM videos I liked watching it till I came across yours unfortunately he sold his DSM I miss that car

[@tangles01]

Jafro > the easy way Also stoked to know Wrap cams exactly the same way. I do at least 1 thing right. Also, damned right I'm hitting the like button.

Everbright Protectaclear might be able to lock your aluminum shine down to where you never have to give it maintenance again. It can withstand up to 545 fahrenheit. I'm currently testing it on various automotive parts.

[@neuronaut8030]

If you or someone you know has Jafro levels of OCD pertaining to DSM motors, reach out and get help. But not Jafro because I like watching his videos. Meanwhile I feel like it's a chore to clean dirt dober nests off of my engine bay lol. But I'm performance obsessed and care less and less about aesthetics as time goes on haha. But I still love Jafro for showing me how to gasket match port heads and polish combustion chambers (the only polished part on my Toyota 2ZZ-GE is the combustion chamber, runners are just ported cause I couldn't find definitive research showing polishing intakes worked to make power versus the micro turbulence a/f mixture from an unpolished intake runner). I still love his videos even if it's just cosmetic stuff like this, it's next level insane especially when it comes to cast aluminum lol. I'd almost clear coat this stuff, he's right "don't start won't be none" haha. Love it.

3:19. Absolutely perfectly timed comedic cut. 🤣🤣🤣🤣

Can’t wait for the 6 bolt f-150 build 👌🏻

[@Jafromobile]

Or the 5.0L Coyote Elantra.

[@Lou-f]

@@Jafromobile good idea, but you’ll have to polish that too…

Exactly what I've wanted. Nice job! Can't wait for part two.

[@BentSpanner]

So much dedication to detail mate. I appreciate your time in to making your style of content. Thank you and keep it up.

[@theactualsalvagedrover]

What exactly went into that ultrasonic cleaner for make it clean the aluminum so well? Was that distilled water? What was the chemical, the dilution ratio? Can it be applied to a smaller tank? Sorry for the entry-level questions, but nobody ever taught me anything useful and you seem to know some good stuff. I watch your port/polish video over and over.

[@Jafromobile]

I spend the most time on this topic in "Galant VR-4 Cylinder Head Inspection". Fully explain the whole ultrasonic cleaner thing end-to-end. Be careful with this stuff, don't walk away and leave your aluminum parts in it. It's also not the easiest to dispose of, but not so bad...

[@802Garage]

My biggest problem with this is that the price of decent sandpaper has gone insane. Awesome work though.

[@Jafromobile]

Right?!?! I have to give credit to Craftsman where it's due... that was by far the most durable sandpaper I've ever used.

[@802Garage]

@@Jafromobile That's at least encouraging to hear! Seems you can either get a lot of paper cheap on Amazon from who knows where or get a small amount of brand name paper for what you would think are bulk prices.

[@gjrt7573]

DAMN..... THAT ultrasonic cleaner that was worth the watch.

[@chadsmith2036]

I love your videos even though I have a 420a. I still have a love for the awd turbo (4g63). Someday I'll own one and all your videos will have great insight to what I'm working towards. Keep em coming.

[@Sonos45]

I polish combustion chambers. If you start dressing up the outside then u need to do paint and it'd be a waste to do paint without straightening the body. Next thing you know the budget has shifted... Why was I building a cheap car again? We still love ya man.

[@Jafromobile]

That's exactly how it works... and while I'm in there I might as well...

[@troykleeman4258]

Fantastic video, Jafro! Question - what recipe do you use in your ultrasonic cleaner? That head came out mint!

[@andrewtrumbo983]

So glad Im not the only one addicted to polishing stuff lol
