Maybe, maybe not. First time I tried it, I had put a couple of sticks of black pipe outside behind the building where they lay for a couple of years. Black pipe rusts up like nobody's business, so I sliced a couple of 1" rings off one end (this was 2-1/2" pipe), put it in a coffee tub with about a 5 to 1 mix (water to molasses), and let it soak for a couple of weeks, perhaps a bit longer. When I pulled them out and rinsed them off, they were both this lovely, gray bare metal, even where there had been a bit of pitting. Can't knock success, imo. Hope it works for you.

Tom, I am surprised you have not 'invested' in a small benchtop blasting cabinet by now and with that huge compressor you have. I have one loaded with medium size glass beads and it is a life saver for all smaller parts that need cleaning, the glass bead don't attack the metal and leave a nice peened surface. The glass bead seems to last a while if you clean the parts before blasting and the cabinets are usually in the 150-200$ range. You would not have fit the back tin (which you probably know but is specific to a 1968 912 - brackets on left with the holes are for the smog pump), but would have worked for many other parts.

The vapor blasting doesn’t hurt good plastic or rubber. The media is suspended in the water and the water is the bearer between the media and the part. I have thrown a couple of scoops of baking soda in the mixture and not sure if it help but what the heck baking soda does clean things.. I’m shocked on how well it works.

Hi Tom, great video, Hopefully this one goes viral! I wanted to let you know that I have been using a product from Eastwood called Fast Etch. I think it is similar to metal conditioner but I have not verified. What I like about Fast Etch is that it seems to put a coating on the metal and actually prevents rust from forming. I have been using Fast Etch as my last step before primer. Before I'm ready to primer an area, and I have all visible rust gone I apply the Fast Etch kind of like my last line of defense hopefully taking care of minute surface rust. I work it in with a maroon scotchbrite pad and then I wipe it all off with a towel. And do a final clean with Acetone. Then I do the primer. Maybe I should be using the wax and grease remover instead of the acetone? Or after I use Acetone? Anyway, you may want to evaluate the fast etch if you need to buy anymore metal conditioner.
@GarageTimeAutoResto3 жыл бұрын
Sounds like a very similar product. Re-wetting and wiping it off is a good call before paint. SPI says not to prime over the white residue. Not sure if you are using SPI also? Acetone should work well. SPI recommend their w&g cleaner... no surprise.

Sand is messy for sure and cleanliness really matters. However if pitted metal shows through the paint later this can be caused by the wildly different paint thickness.

Good. Sand blasting could be the best way to erase the rust. Nevertheless, in France, we have something like evaporust we can find in Restom brand, and metal brush on drilling machin, and sand discs. But after the metal is clean, I put quickly PHO from Restom, à phosphate acid liquide, with a piece of cloth to prevent the metal from the rust, that create an oxyde that protects the steel, and also Increase the grip of the paint. I use epoxy primer on thin metal sheet and black epoxy for other parts directly over the treated steel surfaces. Nevertheless, removing the rust always needs tools, lot of time and self-sacrifice. Californian weather is also better to avoid that the rust comes back, than the weather in Paris, that is also truth!

California cars are lucky to last longer if they are well taken of. It seems every epoxy primer manufacturer recommends something a little different.

The black that the converter goes on the metal is ferric phosphate and is an inert layer that won't react, it's not rust at that stage once it goes black. However it only reacts within a few microns so if you don't clean most of the rust off it will not penetrate deep and the rust will return. So basically use multiple methods, start with electrolysis, then wire wheel, clean the metal then use a converter which will seal any missed rust and react with it, wipe clean with water, dry then prepsol and finally etch primer.

I've done a ton of experimenting with various methods. Parts that can be taken off and soaked are easy. I bought an entire garbage bin, filled it with hydrochloric acid mixed with water, and then another bin with water and baking soda. I first take off all the surface rust as much as possible with a wire wheel to make the process smoother, then soak it in the acid for a day, then right away over to the bin with the baking soda for 10 or so minutes, dry it with a blow torch and finally brush on a solution of phosphoric acid to remove any surface rust. I would dip it in phosphoric acid straight away but I can't get hold of any larger quantities without having to order it online. Wire wheeling off all the rust for parts that are on the car is much more difficult, but you need a good wire wheel with very solid and rough strains that doesn't fold and can cut into the hard crusty rust. Flap discs work in some areas but not really good on sheet metal since it can burn through. You need something that is hard enough to cut into the rust but soft enough to follow the shape

Thanks for sharing. I believe the dupont uses Ospho acid, but not sure how strong. Dupont adds chemicals to prevent flash rust and ensure paint adhesion. When you use straight acid, you must make sure it's neutralized properly or it may affect the paint years later. That is why I recommended a product that is engineered to work with paint. Oddly enough they recommend rinsing it off with water. Muriatic acid or swimming pool acid is also cheap and strong, but boy that metal will rust again in a hurry.

Great video Tom, What type-grade of sand you use? Thanks
@GarageTimeAutoResto2 жыл бұрын
Thanks Pedro,. I use genuine Huntington Beach sand. It's not recommended for blasting, but I strain it through a perforated sheet metal. Wear a respirator if you do a lot because it's not good for your lungs. Otherwise, I'd goto harbor freight and get their corse sand.

Tow questions. 1. What kind of welding you used on this video 2. What classic car do you have in your garage XD looks like a big block

What about a piece that you aren't going to repaint and you want to just slow the rust spread? My car has some patina and planning to leave it that way but have noticed some rust bubbles at the bottom of the door. If I remove the door card, should I treat it with a particular product to slow the process?

You can spray cavity wax on the doors interior. If you have bubbles through the paint, then significant damage has already begun. You are most likely looking at cutting out and replacing metal in your future.

@@GarageTimeAutoResto Thank you! I'll check that out. Yeah, I'm going to avoid proper repair for as long as possible because given the originality of the car, if I fix one spot I'm going to end up having to do the entire thing or else it'll look weird to have just one repainted section.

Good choice. Enjoy the car now before you go and fix all the patina. That is what I did with my 356. Owned it for more than 25 years now. I developed a bond and now will never sell it.

Thanks for this. Rust converter is a chemical process that transforms the ferrous oxide into another chemical. SO you don't have remove the black residue. That inert black stuff is the sign that you have completed the mission. Maybe a DIY wooden frame during mechanical processes would be an assurance against warping risk,

The problem with leaving the ferrous oxide is that most often there is rust underneath it. That is why I prefer to keep going until nothing turns black.

Tom. On the pits, I use a fordom or dremmel and a fine carbide burr to brighten each pit. Also I found carbide dentist drills on eBay for a couple bucks for 5-10 to the box. They work super but it takes a lot time. On old 356's after we get the paint off, I use a Aspho Formic acid to highlight the pits, then grind them off. Hoods and fenders have allot of old rock chips they will have fine rust pits. It's just as good as a spot blaster and much less clean up. Nice job on the tins.

Thanks John. Good tips, but now my teeth hurt, ha ha. We are in alignment about using acids to spot rust. Same chemical different name.
