Or is the heat process in powder coating hot enough that it will melt the solder on the bottom of the tank? How do you find a decent firm that will paint the tank the color to match your car? Obviously it is not black.
I don't know the composition of the solder Ford used but powder coating temperatures will melt most tin/lead solders in the 50/50 range. The higher the lead content, the higher the melting point. You'd have to be in the 5-20% tin range to be above PC temps.
I don't know of any "sane" person that would try to PC a used tank. I suppose it can be made safe but expect to pay more for flushing the tank and/or filling with nitrogen.
Why not just paint the tank with the car?
Unless it's a speedster, tanks never (well maybe 26-27 tanks in the cowl) painted to matched the car, they were galvanized. So for a tank in the car, the cold galvanized paint/coating sold by most places would be a close match to the original color.
Read and understand the above. The early tanks were galvanized, but the later oval tanks were zinc, and it's rare to find one with good plating on it
??? Zinc = Galvanize.
Dave wants the tank to match the car color.
Be sure to use a paint that will not be affected by spilt gas. This was discussed on the forum previously if you want more info.
Rustolieum for me. Cheap, easy to apply, easy to touch up. The tank is hardly seen, seldom needs attention, and basically only you look at it when you put gas into it. JMHO
It will depend on the powder you use. We once had a job painting 1500 WOODEN toilet seats a day. That powder cured at around 115 Deg F. Most powder will melt the solder in the tank. Dan
The tank is off my speedster. I took it to a radiator place to resolder he outlet. He obviously dropped the tank a couple of times due to the big dents, and put a lot of scratches on it. Not much I can do now except repaint it. It might even be worth it to get a new tank and paint that rather than trying to repaint or remove all the old paint and repaint it.
Besides I do not have painting skills and rustoleum just doesn't do it. You really need someone who knows how to mix paint and do it the correct way.
