My experience on boats is that the epoxy resin deteriorates in sunlight. Where I have used epoxy resin with glass fibre for repairs I have coated it with a polyurethane resin gel coat for protection.

Epoxy is a learning curve for me thats why I have been asking for ideas, as in my trade polyester is standard. Epoxy is rarely used, only for the odd small repair.

Not saying this will not work, but such filled epoxy mold surface resins are standard items available from pretty much every supplier. No need to risk loss of time, materials and money, just use something that is proven to work.

By the way just like to say I used the fillet wax from Ec, works very well. Big improvement over what I have previously been using

Group: Forum Members Posts: 14, Visits: 592	Ok so talking with somebody, epoxy compatible gel coat is probably not the best route to go. I'm finding the whole epoxy compatibility thing a bit annoying. I actually like to work with polyester but on a project this size shrinking could be a big issue. So I continue to research. I've just completed a project, it a blanking panel made all from polyester for a friend, he's happy with it.

Group: Forum Members Posts: 14, Visits: 592	ajb100 (17/06/2014) To make a mould that size, you would be much better off using a designated tooling resin to build the mould to minimise shrinkage and any warping.When I built my roof mould, I used EC Uni mould system and it came out great. I used 5 layers of 600gsm for the main part and found this to be a little whippy along the length so ended up fibreglassing a few planks on it to give it more rigidity Good info. I like the look of EC uni mould system, but I can see it being quite expensive to do this. I have found 20 litres of epoxy that is almost out of date so this could be a good option in conjunction with ec epoxy compatible gelcoat and maybe power bound csm , but I've not used this setup for a plug before. But I can see it being good for minimum shrinkage Edited 11 Years Ago by winty
