I recently purchased a Brookville roadster body, it came with some type of red oxide paint on it. I would like to spray it with PPG DLPF epoxy primer before the winter comes. Do I need to strip the paint down to bare metal? Or can I just ruff up the existing that came from Brookville. Any knowledge on the subject greatly appreciated thanks.
i would at least give it an orbital sand all over prior to applying the epoxy, theres no real way of telling how well the body was prepped prior to applying the red oxide stuff. if you just give it a scuff , the red oxide might let go under the epoxy and ruin the whole job in the future.
With 99% of coatings you can lightly sand to leave a profile and then apply the second coat.I would recomend that you read the product data sheet and make sure that it doesn't say anything about non-capatible coatings. Otherwise, spray the hell out of it and make sure that you use the recomeneded thinner. Sam
It would be best to strip all the paint off to bare metal then etch prime it and prime it you can try sand a small spot with 320 grit or finer and spray primer over it and see if it reacts if it doesent do anything goofy u can go over it and not strip it i would strip it if it was mine
Painting anything is definitely NOT my strong point, but I have had some experience with Brookville's red oxide. I don't think Brookville really intended this to be left under any finish, but more spray it on for protection until you are ready to prime & paint. My Brookville doors had their red oxide on it. It sanded off ridiculously easy down to bare steel. And many spots had a bit of surface rust that you would never see if you left the red oxide on. It all DA's off so easy. I would probably recommend taking it all off. I even wiped the primer right off of tough to get to areas with a rag & lacquer thinner. It takes a little longer, but probably worth the effort to protect the beautiful new body. Let us know how things go! Dan
Don't know about the Brookville primer specificaly but I have found this to be true of any oem part with primer, I have never, nor have I ever met anyone else that would use the factory primer on replacement parts....no matter where they come from....sand it off and metal prep.
To me... if you spent the dough for a brookville, then your planning on this being a higher end car so don't skip an easy step. The first steps are the foundation. Good luck
Don't trust anyone else's prep work. It's worth it to strip it down and be sure of what you've got underneath! You're going to sink a lot of time and money into your project. Start with a good, known foundation!
PPG's DPLF needs no etch primer under it...it's designed to go over bare metal. I, too, would remove all the red oxide before spraying DPLF... R-
i would'nt think twice about removing that red oxide and putting a high quality etching primer on it.
red off dp on it all starts at the begining.... would you a multi thousand dollar paint job over $25 primer?????
I would also suggest staying clear of the etching primers. I prefer to use an two part epoxy primer over a surface that has 80 grit DA scratches. I am currently trying Southern Polyurethane Inc. products. So far I am impressed with the quality and price. Tom
I was initially going to suggest that you contact Brookville directly and find out exactly what this red stuff is ... BUT ... then I read the other posts and what they all say makes a lot more sense. I agree, remove the red and start fresh.
