yeah its real easy, you need a release agent, i use kantstick wax, polish the bonnet with that, get a good few layers on there. then gell coat, either brush or spray the gellcoat onto the waxed bonnet, then fine fibreglass tissue, stick that ontop if the gellcoat, and then dab the resin into it with a brush, once the tissue is coated, use a paddle roller to get any air bubbles out. next is the chop strand glass to bulk it up, cover the whole bonnet in it and dab the resin onto it, coating it all, and use the roller to press is flat and get rid of air bubbles. do a few layers of chop strand to make the mold as thick as you like. if your only doing a couple of bonnets the mould doesnt have to be very thick. now add some battons/peices of wood accross it to keep the mould rigid, just stick the battons on with resin and coat in chop stand. you can either pull the mould off before its fully cured, so 2 hours after, or leave a day or so and crack the bugger off, use a plastic scraper to get between the bonnet and mould. dont be scared of giving it some grief to get them apart i normally leave the mould for a week or so before casting from it, to get it nice and dried out. as with the bonnet, wax the mould, about 10 coats, the last coat put on nice and thick and dont buff it off. now its basically the same as making the mould. so brush or spray on the gellcoat, then apply tissue, resin, then roller, then add 2 layers of chopped strand, making sure you get it nice and even, and also put more towards the edges. give it a right good rollering, the more you roller it the stronger it will be. i usually use 1 layer of tissue, 1 later of fine weave fibreglass, as its really strong, its like carbon fibre but real cheap. leave the bonnet in the mould for about 2 days, because if you take it out before its cured fully it will warp like a biatch anyways, hope that helps. oh, if you want to make a carbon bonnet, there is an easy way, insted of the tissue, you use carbon, and the gellcoat has to be clear, and you have to spray the gellcoat on with a gun, get a good few layers on, so its thick enough to sand and polish. leave it 20 mins so its half cured, then spray another layer on, then you lay the carbon on and roller the shit out of it untill there are no bubbles at all. then just bulk it up with chop strand, mix one of the small black humbrol model paint tins into your resin, to turn it all black carbon is £25 a sq metre by the way kevlar is about £15 and looks awesome on a bonnet. i use fibreglass because its cheap for racing/crashing
