You are right sanding gelcoat wont give as smooth a finish as normal gelcoat it will need painting,but i dont agree that normal gelcoat is easy to sand far from it.Actually rather than use gelcoat your best using Duratec but its so expensive.Ive also used durabuild primer,this sands to a high gloss sheen and can be used and gives a nice finish to your plugs and can be directly moulded off after waxing of course.

This is really helpful stuff guys, thanks! So if you make your plug and then barrier it up, lay up you lower mould, remove the barriers, then lay up your upper mould you should get the perfect two parts for a seamless join (in theory!)? Surely as you lay up you two halves in the moulds you end up with scruffy overhangs which can only be cleaned up when the resin has set, which would prevent you from closing the two halves together? Is the fibreglassing on the inside really vital as I am only going to be making hulls of around 16" or 400mm in length so access could be an issue! Can anyone explain the pros/cons of polyester vs epoxy too, both seem to be used for this application? Thanks again, gazz.Comment
