Okay IM MOST likely going to have a shop do the work, however curious in the event if I wanna take a shot at it.


Getting a carbon fiber rear difuser that is not clear coated from the company. What is the best way to prep? Seen quite a few people saying use a 2000 grit wet sand and then go up to a 3500 and then clear?

andy knows all about carbon fiber

Sounds reasonable.

I would probably make a finish @ 5000grit wet rather than 3500 but that's personal preference.

yep, old andy is your guy, pm him or wait for him to see this

looks fool

Depends on the porosity of the laminate. Lots of aftermarket parts don't look very nice fresh out of a mold without any post process finishing. If there are any small pin holes urethane clear will not like it.

As far as prepping the surface for paint, honestly a red scotch brite pad (or around 400 grit wet) will prep the surface adequately for clear. I don't know about the guys who are sanding to 3500....Clear wants something to stick to, ultra smooth finishes prohibit this.... Not to mention the process of spraying itself can't leave anywhere near a 3500 grit finish, so all that extra sanding is needless, and foolish if you ask me. You work your way up to the thousand+ grits after you've sprayed your urethane clear, and have begun the cut/buff/polish process once the material adequately cures.

Sent you a PM, you've got me curious now.
