Hi all I want to make a split mould for this air intake for my car out of Pre peg ' I bought the uni mould kit but have since found out its no good with the higher temps with the pre peg
Could I use the glass fiber mesh out of the uni mould kit with the high temp resin and the EG60 Epoxy Tooling Gelcoat .

or if not can you make a split mould using the tooling pre peg ?

1200 is wayyyy too fine for a pattern coating like high gloss coat. Need about 240 at the finest, preferably 180.

In any case, unless the plug came out of the mould and only left the gloss coat on the surface, then that isn't your issue - just thought I'd mention it.
