MUSIC
I try and use 50’s/early 60’s recordings taken from acetates with no identifying artist or song names this way I am doing my best to stay within copyright restrictions and giving some real cool recordings a chance to be aired, albeit not knowing who the artist actually is. I have unfortunately used music after seeking permission from an artist and this music has now been released causing me issues, this means that from time to time some of my videos will have to be edited and reloaded. This seems crazy to me as I’m actually generating a fan base for artists to only then be penalised for promoting them. If you are a music artist producing surf or rock and roll music and would like me to use your music then please contact me as I can give you free air time in front of a guaranteed audience.

Great video thanks. I do a last stage before painting - treat with phosphoric acid, Kurust for little bits. Love to see the CA van. My Dad had a 1960 CAL Kenex Yeoman, 3213 K. Mid-60s I got the job of panel beating & painting the o/s front wing when a malicious lamp post attacked it. Managed a total no-filler repair & brush painted the deep red & cream to match with Tekaloid. Keep up the great work, your tremendous efforts are appreciated!

Again a very informative video Trev. Yours is about the first channel to mention the use of thin "plastic" sheets when applying paint stripper whereas (if that's the right word) it makes a tremendous difference. ATB Marc - Belgium

[@Conservator.]

Yet another top video, thank you! I think the temperature will determine the speed of the process whereas the amount of acidic acid should be proportionate to the amount of rust to be removed. And the amount of water should just be enough to keep every bit in contact with the solution.

[@1963TOMB]

Thanks to this video I refreshed the front of my Morris 1000 Traveler this summer. Once everything was stripped to bare metal and de-rusted as much as practicable with a knotted wire brush I used a 1-2% solution in a wheelie bin. Twice a day I removed the parts, washed and wire brushed the rusty areas, washed again and then back in the bin. Took a few days but all the rust was removed. A final rinse and then dry quickly with a heat gun before than removing the light grey oxidation that formed, wipe down with degreaser and finally prime with epoxy primer. It worked a treat. I then did the same with 4 steel wheels. All painted and car back together. I'm about to do the same with the back end and the kick plates etc. but I'm expecting it to take much longer in winter!

Good morning Trev, more good information. I will certainly give this process a try. Always more information and education that is useful. Take care.

[@guillermonieri4203]

Thank you. A great alternative. I normally used water vinegar with salt, and let them seat for 1 or 2 days, depending on the amount of rust; then rinse them with water, and soak them for a few minutes in water with baking soda mix; and give them a final rinse with water. Please keep on doing videos where you "teach" how to do things.

[@sdunca4864]

Trev! Bravo on the re-do of this vid- great info! You give a great tip about the paint stripper at 2:45 or so... Might want to consider if you dont want to use so much stripper giving the piece a brisk stainless steel wire brushing first... gets the surface oxides and generally the dirt and crud off so the strip can work directly ON the paint- and you dont use quite so much of the chemicals to boot! Love the channel and gotta say well done indeed!

That plating was zinc and colour passivate 👍 Those parts came up lovely! Good old citric acid!

[@bobbastion7335]

If you're not in a hurry for the part, you can use the old school Molasses/water bath at a ratio of 7 parts water to one part molasses. We put entire body parts in a molasses bath and the good thing is that it removes rust ONLY (acid just keeps eating). The downside is that it smells pretty funky in the summer so you'll want to keep it away from the house and put a lid on it to minimize evaporation and to contain the smell.

Great video Trev. I learned a lot and will give the "Secret Solution" a try. I have been looking for a good alternative to both sand and soda blasting as I think that removes too much " good " metal.

Nate Hankins Thanks you get it 🤩 hallelujah 🤩most people trying to make a point are always saying ahh yeah but there’s a better way..... of course there’s a better way, there always is but you can’t get much more simple than a bucket and some elbow grease. We’ve got two 700 cfm compressors and a dedicated blasting booth at work but what would be the point in showing that off. Cheers much appreciated Trev 👍

[@davebell4917]

There's a lot of things you can use that citric acid for, and the "food-grade" rating keeps the options open. If you're in a hard water area, it works for kettle de-scaling, and costs a lot less. But I'd keep the kitchen supply separate from the workshop supply, maybe re-use a jam jar, and label it. You mentioned alternatives such as white vinegar, and I can confirm that works, helped clean the bottom of a saucepan and it was within easy reach in the kitchen.

[@wibblywobblyidiotvision]

Hi Trev. Love your channel, loads of really good info, particularly all the panel beating stuff. For rust removal, though, I can't recommend anything more than electrolysis. It's dead simple, all you need is some sugar soap, water, some scrap steel and a DC power supply. There's no need to worry about leaving your parts in too long, no need to neutralise the parts after treatment, and no need even to strip paint or to degrease - it'll pretty much all come off during the process, especially if you drive the process with a DC welder as opposed to a battery charger. The reason I prefer electrolysis over anything else is that it doesn't remove any good metal, and converts the rust from the dreaded red death, Fe2O3, to stable, non-cancerous, Fe3O4 (magnetite). I use it for rust removal on machine tools, lathes and the like, where precision is important, and abrasives are pretty much a no-no. As for the whole hydrogen embrittlement thing, I used to worry about it, but decided to do a test. Took a bunch of identical springs, rusted most of them by dipping in and out of salt water. Kept a couple of rusted and a couple of clean springs as controls, chucked the rest in the electrolysis bath, DC welder at 20A for an hour or so. Pulled half out, dried and oiled them, then hooked up the battery charger and left the rest electrolysing for 2 days. I then pulled them to destruction using work's little load cell and a hand winch. Result - no discernible difference. Less than .5N spread between all the springs, they all went to plastic deformation at about 30N. No premature snapping. None of which is to say that hydrogen embrittlement is not a real thing, but I couldn't see the effects.

[@THIRSTYGUMS]

the embrittlement comes from the acid surely?

[@diycarhome9151]

Is Trev coming from the UK? I'm here in Canada working on a 1993 Plymouth Acclaim. Bought it used low Kim's. Previous owner never washed the road salt off from Winter. The factory painted all the rims and suspension parts with that thin electrostatic black paint. Well the salt ate through it and rusted everything. So I disassembled the front and rear ends. Washed the oil, dirt and grease if any. Used paint stripper, scraped, wire brushed and rotary wire brushed with a electric Die grinder. Then filled a plastic tub to submerge the wheel rims and soaked them for two days in a 50/50 mix of Muriatic Acid and water. Removed all the rust deep into the pits. After used Ajax and liquid soap to wash and clean the metal, flushed down with water. Then used a milder acid called metal prep to prevent flash rusting, washed off with water again then sun dried and ready to Prime with metal Primer. Two to three coats of Primer, lightly sand and top coat. Don't waste your time removing heavy rust with other vinegars, mild rust removers etc. you will there to Christmas. Use Muriatic cleans fast and is Violent. Cleans heavy rust fast. Sandblasting can be use after. Sandblasting can not get down in the pores. Also did electrolysis using a battery charger. Ok to a degree. But Acid gets it cleaner faster.

[@Giblet535]

Evap-O-Rust and electrolysis are all I've used. I'm definitely going to try citric acid. These parts turned out perfectly. Thanks!

[@darkshadowsx5949]

I've seen a test where Evap-O Rust did absolutely nothing to dissolve rust. the test was done by a youtuber who tests various products equally and scientifically. muratic acid which I've personally used will dissolve the rust in about 10-15 minutes soak. I usually dilute it to about 10% Hydrochloric acid instead of 37.5% which muratic is. products with phosphoric acid are the next quickest. vinegar works too but is rather slow but its also pretty safe as you can drink vinegar without a problem. if you prefer the non toxic and bio degradable properties of Evap-O Rust then go ahead.

[@Giblet535]

@@darkshadowsx5949 Evap-O-Rust doesn't work if the metal has oil on it. I saw that video. Something was off there, maybe oil, maybe something else. A dip in any strong acid will emulsify any oil, then it can be rinsed and tossed into the Evap-O-Rust for a week. There won't be any rust on it after that. Unlike acids, the metal won't turn brittle or soft, and you don't have to hurry to prime it because it won't corrode until you rinse it really well. It's not as fast as other methods. Other than tax refunds and pizza deliveries, how often is faster better.

Fantastic video serious Trev. Thank you

[@GridIndustries]

I know someone else suggested it, but a small media blasting cabinet would have been perfect for those hinges. Probably not so good for those thinner metal parts, depending on the media used. I like to use POR-15 metal prep on a lot of things because it leaves a phosphoric coating afterwards to protect the metal. It almost looks like you used a single stage paint for the hinges? Your panel gaps look PERFECT. Love seeing the progress on the van and appreciate your tips and tricks massively!

[@anthonyprice5596]

Definitely use washers, the paint will be ruined under those bolts, and use stainless bolts and washers. More importantly, when are you going to show us how you get your hair so perfect?? Love the videos keep up the good work, are you going to Beaulieu for the custom show this year? Be nice to buy you a beer and have a chat, or any other beverage that takes your fancy.

[@stevemcilroy9518]

What a great idea about paint stripper. I've been trying to strip the paint off the Lada Riva (10 tons of Russian pride) bonnet for weeks, ended up more like a polish. Shined it up a treat, I'm going to try that tip tomorrow and cover it with paint stripper and cling film. "Oh those Russians" ( Boney M, Rasputin)

[@marty3469]

That citric acid de rusting came up tops 👍. Had you thought of using dome head Allen bolts in stainless for securing the hinges on .. I used stainless countersunk Allen bolts for my Escort van hinges instead of Phillips screws , looks way better 😎

[@Tony-Waldron]

How can you go wrong, even when you make mistakes it still looks great :)

[@fanwlkr]

Nice, wish I could just dip my entire car like that without any problems :) This is the first time I've seen this exact technique, very interesting. This seems like a very effective way to get rust free part, so I'll give this a go. I've seen in some similar things where they use fluids to interact with parts, that moving the parts about horisontoly when submerged can remove some air bubles that get trapped. Don't think hydrogen imbrittlement will do much under 200 celsius, but I could be wrong.

[@PearComputingDevices]

I would try vinegar with citric acid. Vinegar is a very good neutralizer. Certainly it wouldn't be bad to give these things a bath in it and maybe a scrubbing with a greenie after. Scotch bright pads are amazing for spiffing things up. Neat video.

[@davidcarmichael8394]

Plating on those parts either zinc or cadmium which has been passivated after plating. If worried about hydrogen enbrittlement suggest place parts in hot oven for 30 minutes after your stripping process. Heating will drive off hydrogen. Information comes from Aviation MilSpecs for Electroplaters. Rather important for the springs you mention.

[@billythebake]

Gonna' mention that myself - you beat me to it. For general purposes on steel, about 450° F. Also useful for critical parts that have been arc welded (esp. w/o low-hydrogen filler) as well as plated stuff

I like to use Dairy Wash from the farm store for rust removal. It is phosphoric acid and a bit of soap. It dissolves rust faster than steel and will leave an iron phosphate coat on the surface which acts as a protection to flash rusting.

[@alexwoods2921]

Handy little tip cheers!!

[@SteveRivett]

I would put the fasteners in a lathe and take the markings off the heads. Hardware store fasteners will look out of place. You can even use knurled bolts (like wheel studs) and turn them down to look like rivets. The knurl will keep it from spinning when you tighten the nuts.
