por-15 to primer

[paulk68]

Guys i am going to strip all of my front end sheet metal down to metal then i was planning on just putting them in dp-90 epoxy primer because they are going to sit for a while. would it be better to stip them coat them in por 15 then can i put the dp90 over the por 15 just so there is never a chance of them rusting. again. just a thought any help would be great.

You will never be able to scratch the POR enough to get good adhesion. Use the DP 90 and save the POR for undercarrige, frame, etc.

por 15 makes a product called ty coat its made so you can paint over por 15 . otherwise you can put some primer down while the por 15 is still tacky so you will have some bond .

don't even mess with por and primer, go bare metal to dp 90, epoxy primer, just make sure to have rust sanblasted clean or cut and a patch fully welded in, you will not have future issues this way.
too many adhesion, lifting etc issue's priming over por

Personally I am not the biggest fan of POR. While I have had a sucsess or two. The falures and headaches far exceed the sucsess

I've been having pretty good luck with using por as a no-sand primer. The tech manuals say that you can use por in place of an etch prime. Once sprayed, just wait till it finger drags(usually 2 to 3 hours later) then apply a primer or top coat over it. I've been doing this for a while without an issues. I'll also say that I haven't done that on any body panels or anything that is cosmetic to the car, i.e. hood, fenders, cowl, etc., but all the parts that I've been sand blasting, such as a drag link, rear end, convertible top frame, etc.
