Hi,

With great difficulty, I got the mould to release from the front bumper. I am happy with the outcome. Just a few questions:

1. Is there an alternative to mould cleaner I can use to clean away the wax?

2. Is there a trick to touching up any imperfections with additional gelcoat?

That's some really useful information especially choosing 800 grit as the coarsest of sand paper. That's a mistake I made on project two. 

I can imagine the trick with the tape being effective. I will use that and see how I get on.

Thanks, making carbon fibre parts must be your profession?!
