I know its a bike bit but....

Hi guys,
First off I apologise for asking about paint on a motorcycle part but I know I'll get good advice on this so here goes....

The tail section in the pics is carbon fibre, it was painted previously leaving a carbon fibre stripe exposed. I want to repaint in the same way. My bodyshop has sprayed it with a high build primer masking off the carbon stripe. Now I have high edges against the carbon stripe and some areas which were masked badly and vary thw width of the stripe.

I have masked off the stipe again and sanded down using 320 then 800 paper which has reduced the edge but has dulled the carbon stripe down, which was laquered before.
What should I do now to make sure I get a good quality stripe when the top coat is painted. Is masking off the stripe with a very slightly narrower tape a good idea?

My paintshop doesnt really know what to do now!!!!

Any help would be appreciated

Andy

Where is JimC when I need him?? but i will give it a shot..first thing the high build primer was the mistake as it built that edge..sanding like you have is part of the fix..get that edge sanded down as best you can and then apply the base coat..on the stripe area you may need to lay in some extra coats of clear to get the stripe area back even then clear the whole thing..

Best idea I have at this time of the morning..

Sam

Thanks for the reply Sam,
How about the edges of the primer which have bled over the stripe, do you think that sanding it off is a good idea to get back the correct width of stripe?
As it was painted before I guess that if I ended up sanding a little too far through the primer, the top coat would still adhere to the original paint/laquer or would more primer be needed

The trick is going to be sanding that thing down and not biting into the carbon if avoidable. i would try to get it down as far as I can and then use a regular 2k sealer/primer that goes on thin. there is a special tape that we use that helps with paint bleeding under the edge of stripes and after I put the tape down I shoot with an intercoat clear to seal the tape edge and then my color coat..once the color coats and graphics are done..then shoot the final clear..this should bury the edges so they are not quite so apparent..

Good luck..

Sam

Use the blue 1/4 inch fine line tape (or thinner if need be) and stay inside the boundries of the exposed carbon. In other words give up some of the width so you get a clean masked off stripe. Resand carefully up to the edge of the tape with fine paper
.Don't add more primer/material.
Dust on the base color, pull the tape and then clear over everything.
The clear will even out your worry of gloss.
Keep each step of the operation clean...
Keep us posted
thanks for the pics!
It can be done
