Right, finally managed to do some more work on the bumper as it's being sprayed soon. I haven't worked with carbon since college but I think it went okay.
If I could do it again however, I wouldn't have bothered going for the pre-preg cloth, as it kept trying to unstick itself on the inside edges because it didn't like being folded back on itself.
Here's a few pictures I took along the way.
First job was to removed the lip along the back edge of the centre bar, I used VERY course sandpaper for this as the final finish wasn't important at this stage...
And now with the lip removed...
Black resin basecoat applied, had to leave this for about 4-5 hours to go tacky before applying the cloth...
Carbon cloth laid in place before I started pressing it into place...
And after the first coat of resin top coat...
Going to go back into work tomorrow to make sure it hasen't destroyed itself over night, and give it a quick sand and a 2nd coat of resin before I polish it up. :)
