Default Have you guys ever painted a rear diffuser?

Thinking about painting the rear diffuser on our car. Am concerned that it will only get nicked up by road debris. Has anyone painted a rear diffuser? How durable was the finish? Thanks

Hmmm, hundreds of gen V's & Vettes on the site & nobody has painted a rear diffuser?

Was thinking of using a clear epoxy paint. The diffuser is black plastic (probably ABS) so, it doesn't need color. The epoxy would hold up better to road debris & give it a nice shine.

what car are you talking about, if it's a MX-5 (miata) in your sig I doubt there are vary many people on here with one to start with.

PLENTY of Vette owners and T/A owners do something called the CETA Mod which involves painting the area around the exhaust.

if that is what you are talking about. but we need DETAILS of what vehicle you are talking about.

NA/NB MX-5's don't come stock w/ diffusers & the question is not related to a specific vehicle, only its' diffuser. Would like to hear from anyone who has painted a rear diffuser as to the durability of the paint.

I have one of the rear diffuser from 6LE and I painted it a flat black rattle can. I live on a dirt road and have not had any problems with the paint chipping

Unfortunately you're asking on a forum where 90% (or more) of the cars don't have diffusers...

Thanks for the reply. Hadn't come back to this thread since around the time of my last post 'cuz didn't think there was any feedback. We had searched around the net & found many Gen 5's, Vettes & others w/ painted (after purchase, non-factory paint) rear diffusers, but none stated anything regarding durability. Was concerned about chipping or a sand blasting effect due to the air passing under it stirring up debris from the road. We're gonna go ahead @ paint it.

Thanks again. It's not really something people pay much attention to. So, info. is hard to come by.

The prep work is key, Is it's not prepped right and the right chemicals applied, like the right primer and adhesion promoter, then yeah it can flake off.

Ask your local auto paint store, they'll be able to tell you the right products to use for your application.

I can understand your thoughts on the sand blasting effect, even with me living on the dirt road i would have thought that it would happen to me. So how did it turn out? Got any pictures to post?

They always made a clear coat, but that one is still a matte finish. Say you had a crazy custom color and wondered what it looked like matte, clear coat dip fills that need. Black becomes matte black, candy red becomes matte candy red, etc.

They make an after product called glossifier, spray it on dried plastidip to give a gloss finish. Site called dipyourcar has best prices, I checked and that's where I buy mine.

admittedly until about 4 months ago I had no idea what plastidip even was, saw it at lowes and used it to coat a work table in the garage, later bought a can of red to maybe use on some interior parts. Just recently became active on the board again and im noticing a lot of new stuff that wasnt availible when I visited regularly in 08-09.

They are constantly making new stuff now. I will say, the stuff is FLAMMABLE and will burn faster than paper. Tested with open flame but no idea how hot it can really get before self igniting.

That would be something worth noting if its gonna get close to the exhaust tips.

I wouldn't worry about dip once cured. Many have used dip for their CETA mod (myself included). I'm on a plastidip page on facebook and there are guys doing valve covers that hold up...I don't feel like looking it up, but I'm thinking dip is good for +200°F.

Just came back in this section. Didn't realize there were so many replies...Thanks everyone.

Just finished modifying the under tray that fills the underside gap between the rear diff & the diffuser & am ready to paint the diffuser. It will match one of the two colors used on the car & is a urethane base/clear (have leftover paint from original paint job). So, Plastidip isn't an option.

Plan to use a plastic primer after scuffing the diffuser & then color & clear. Diffuser had been the stock black ABS plastic color, no paint.

Saw the request for a pic & will post one once painted (wasn't ignoring you, just hadn't yet made the undertray mods & wasn't sure whether the mods would effect the diffuser). So, was waiting to remove & paint the diffuser; is also why I started this thread early.

Oh yea she'll be pretty.

Because diffusers find lots of rocks and whatnot I suggest spraying the final product with CLEAR plastidip then coat of their glossifier to bring the shine back. That combo is essentially a clear bra type protectant without the hassle of install and much easier removal.
