Clear-coating Carbon Fiber Frame: Question(5 posts)

Clear-coating Carbon Fiber Frame: QuestionBigFatSal
Sep 10, 2003 6:26 PM
I'm clear coating a high-modulus carbon fiber frame. The frame consists of carbon tubes, joined with aluminum lugs. The joints are smoothly blended so no joint can be seen on felt between the lugs and the tubes. It's a Look KG 381i frame.

It'a a very nice frame but the matte finish is very delicate and the white decals are very exposed. A high-gloss clear coat will look great and most importantly give the finish and decals some much-needed protection.

The question: Will a polyurethane-based clear coat be okay on the carbon fiber??? I'm sure a lacquer-based coating would be chemically too strong and could potentially compromise the frame. I'm working with a custom motorcycle guy who's also done some lowrider bikes. Sounds like he knows what he's talking about but he hasn't had experience with carbon.

Thanks for your help.

I send mine to Bike Art in San Diego, they know waht they are doing and they charge only $95.00.
They did an austanding job with 2-3 layers.

I presume this is a pre 2003 model? I think for 2003, the one thing that Look does do is clearcoat the decals. I know my '03 381i is clear coated already. Its one sweet ride, enjoy it. I can't help you on the clear coat though.

High gloss? Are you insane? I have a nude Look- presumably the same frame (I think it is called BBQ). The finish is NOT that delicate... and the matte finish is part of what gives it its stealth cool look (no pun). If you wanted a frame all shiny and lacquered up, you should have picked a painted "team" frameset...

I have 5000 miles on mine, and NO problems with the finish- and the only decal issue is on the fork- and that is from the speedo pickup mount.

I'd worry about reactivity between the finishes- and your potential glossy finish eventually just peeling away like a bad sun burn!

Besides- you can't exactly sand it all down and redo it if you "ehf-it all up."
On a frame that nice, send it to a pro (nm)lampshade
