: Painting Frame - Preparation question?

Well I can't afford to have mine sandblasted and powdercoated. Today I powerwashed it, used paint remover to get most of the old paint off and it is remarkably clean.

I intend to use "Rustcap" spray paint as I know it is very tough from using it on the stepbumper on my 69 Chevy pickup. I hit a tree with the bumper and the paint did not chip and it was a lot rougher than the frame is!

Does anyone know of any sound reason I should NOT do the frame in this manner?

Are there any other inexpensive (Less than $100.00) methods to get a very good looking frame that will be easy to touch up?

I am putting all my money into Baer brakes, Hotchkiss suspension and polygraphite bushings and frame mounts.

For $100 you could use PPG DP90LF which is a semi gloss black epoxy primer. I like to use the GM reconditioning black as a top coat, or use the Eastwood underhood black. I find using a spary gun much better than using a bunch of spray cans, plus the end result will be more durable.

A lot of posters to this site like the POR, but I find it hard to work with and the above method gives excellent results with good corrosion protection.

The problem I may have with POR 15 is there is some paint left on the frame even after powerwashing and paint stripper. I have written to them but my understanding of POR 15 is "no paint" bare metal only.

My experience is that POR can be applied over other paint without problem, either accidentally or on purpose. I would think it would be OK on a frame with some old paint left on it. The only place I've had a problem getting POR to stick is on bare, smooth metal. It needs just a little surface texture to adhere well.

Does anyone know if POR 15 will stick to that concrete like stuff on my frame. I think it is the soundeadening stuff used in the tirewells. My frame has a lot of it adhered to it from the door hinge area to behind the tire wells. I have scaped it flat in most places but it is near impossible to get off. When a big area flakes off, the metal under it is still shinny and flat so it is not rust. More of a gray brown color. I know you can paint a garage floor with POR 15 so it should stick I think, but I would like to know for sure as it is a ton of work getting a frame off and I don't want to do it again!

One more Question! How much POR 15 to do a frame very throughly and how much of their semi gloss top coat? Pretty expensive and I don't want to buy more than is needed.

Thanks for all the responses and yes, I have done a search and read about every POR 15 post going back 100 days!

Redrum, I.m still new to this but, when I decided to restore a 69 velle I looked at it like building a house, start with a good foundation (frame) use a good grinder with heavy duty wire wheel to clean the undercoating etc. off the frame. I used POR15 I sprayed three coats, still had little left from the qt. for touch areas, used half a quart of chassis black. put the rest in a glass jar, need to use sooner than later. It was well worth the $.
