Gelcoat is polyester and available from fibreglass suppliers in brush-on and spray-on formulas. You need the clear (opaque) Gelcoat base to add the pigment to – not the white. The yellow colour is RAL 1018 as shown at the top of the Weta Wiki – if you approach a gelcoat supplier with that number they should be able to match it. I’d suggest using a set of inexpensive electronic kitchen scales to weigh your resin/pigment. Cover them with cling-film first to prevent any overspill damage.

And so I have a couple of questions regarding that: 1) Could you recommend which gel coat to choose (available in EU)? 2) Is it possible to buy a color gel coat that suits Weta yellow hull colour? 3) I find it difficult to perfectly match proportions of resin VS hardener, e.g. 100:1 means 100 gram of resin requires 1 gram of hardener. How to measure exactly 1 gram? Any tricks? Thanks a lot in advance, Michal Author Posts You must be logged in to reply to this topic.
