my is frame painted with rattle can question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

original_balzer · 06-15-2008, 03:32 AM

The previous owner painted the frame with rattle cans. After he had it sand blasted. My question is do I need to take it back down to bare metal or just scuff it up real well?

I know that rattle can paint is not as good as real paint. So is it going to cause a problem being under a product like por 15 and chassis black?

The PO said he put 2-3 coats of primer then there is 1 coat of stupid silver on the top.
Rustoleum is the brand he said he used.

IIRC, and its been about 5 yrs now, POR15 needs bare or sand blasted metal to adhere properly. The running boards of my 2N ford tractor, all I did was a wire wheel on a drill the heavy rust off. Its holding up ok but it aint no trailer queen.

HTH....have fun.....don t. .....

My 69 stepper has been done the same way. I know I have to strip it down and start all over again. Thats the only POR-15 is going to stick.

Thats what I was afraid of consitering I dont have aceass to a sandblaster.

So whats everyones oppinion on paint stripers such as the aircraft stuff? Would that be good enough to take it down to bare metal?

Perhaps I should just get all my frame mods done and send it off to be sandblasted and powdercoated.........

That's the best idea! If your doing mods to the frame, why would you paint it now?

IM not panting it now. I just thought about the rattle can paint the other day and realized Id probably have to strip it back to bare metal. It would suck to get everything done then a year from finished the rattle can paint start releasing on me. Call it foresight if you will. I doubt Ill get it powder coated though. Thats probably out of my budget.

I have to voice another opinion. I have used POR 15 several times on many frames. It does not stick worth a darn to a nice clean frame. If you sandblast the frame, I would go ahead and let it flash rust. POR 15 is designed to be used over rust. If it were my frame, I would sand down the whole frame (using like 50 - 80 grit), not all the paint away, just really rough and then let it sit outside, or spray some water on it and let it sit for a few days. Then POR 15 the frame. If you put it on a smooth fame it will peel right off.

I agree.

You should rough it up & use a good etching primer.

cdowns · 06-15-2008, 08:27 PM

most rattle can paint will wash right off with laquer thinners no need to blast

**leddzepp** · 06-16-2008, 03:02 AM

Put some chemical stripper on it, wash it off, let it flash rust a little, then POR 15.....done.
