i am trying to decide which would be more durable on my frame,control arms and the firewall,por15 chassis black or acrylic enamel(like centari) with some flattening agent. can you spray por15?

I would definitely use POR-15 on the chassis. It can be applied with a sprayer, using their solvent. http://www.por15.com

I used POR-15, scuffed the firewall, and spray painted with Eastwood's Underhood Black. It looks good. I did use Chassis Coat Black over the POR-15 on the suspension parts. Both look very good. Good luck.

I find that the black POR15 is kinda hard to spray for some reason, clogs up the spray gun. I have much better results thinning and spraying the gray, then waiting about 5 hours & painting over with any kind of enamel. The POR15 should still be a little tacky when the top coat is applied.

Good Luck!!

I sprayed my floorpan and underneath the car with two coats of DP90. Let each coat dry five days between coats. After letting the last coat of DP90 dry for 2 weeks, I scuffed everthing with 3M green pad and applied Eastwoods underhood paint. Im telling you its a perfect finish and very tough.

I have used the Por and I don't like it, its way to thick looking. You don't get any detail in the metal with the Por(I'm talking die marks in the metal when it was stamped) The precedure I used above was applied on a completely stripped and metal etched surface, the results were amazing, and took alot of hours.

I know the por is tough but so is the Dp90, I could wack at it pretty hard and I probably would not see metal. Also the eastwood paint will touch fairly easy with a detail gun if you do happen to chip it in the assembly process. I have noticed that the por is kind of hard to touch-up, and it can'y be sanded very easily. Well this was my 2 cents worth.

On my frame I used the Dp90 (two coats) and then applied the frame paint from eastwood, again it looks very professional.

I'm with 70SS. I don't especially like the POR finishes. They are hard to brush, especially on a smooth surface. They work a little better on rough rusty panels. I also don't like to spray it as it is very difficult to clean up. Also did I mention the UV sensitivity problem?

I have used DP90 and in many cases I don't think it even needs to be topcoated. It is semi black in it's natural state. If you do top coat I have used GM Reconditioning Black with good results.

Yay, I like the finish of the Dp90, but this primer is also uv sensitive. The Eastwood under hood paint replicates the Dp90, and is more convient to repair if a accident happens. Mixing the Dp90 and spraying it is not very healthy and not as easy as spraying the Under Hood Black.

is that eastwood paint a spraybomb?i did my control arms with spray bombs after i blasted them,about five years ago and now they look like crap.i want something that is going to look good for a long time.i hear the gm recon black looks good but is not that durable.

You can buy it by the spray bomb or by the Quart. I buy the quart, its cheaper that way and you can mix it the way you want it.

In five years it looked like crap? Is this a driver or Sunday cruiser?

I've used both POR 15 and eastwood paints. I sprayed frame,firewall with POR 15 and chassis coat semi-gloss turned out great just follow POR direction for reducing with solvent.
