A quick question as I have been unable to find a definitive answer on the web site!

Hi Toolchimp,

Sorry no-one picked up this question when you posted it, I've just spotted it so I thought I'd answer for the benefit of others.

Unimould tooling gelcoat is black as we supply it. Black is great for seeing scratches and so is generally favoured for tools (so you can see how well your polishing is going etc.) but I agree than in your specific situation a brighter colour would make seeing the line that you've made with your Easy-Preg a little easier, although I think it practice (and I've done the exact thing you're describing myself) you would not have any problem seeing how well aligned the prepreg was.

However, if you really do want to re-colour the gel then I would suggest adding some white pigment to it to make a grey gelcoat. Our Polyester Colour Pigments would be compatible (and the right choice) for the Uni-Mould Tooling Gelcoat.

I hope this helps,

Matt
