That's the book. Excellent tome giving you all the information you require to make your first GRP model.
BTW, practice on something small first, that way you won't mess a lot of hard work up.
I lay-up using the following methods.
PVA and wax the mould. If you're using the lost foam method, ignore this part and the next
Brush in a thin(ish) coat of Gelcoat, wait until this has set and is tacky- an hour or so in good temperatures.
Prepare my chopped strand matt (CSM) by cutting out appropriate shapes.
I use 400 gram CSM, and I use two layers for small lay-ups, with a few extra bits of extra in areas of stress, or where the boat is likely to take a whack at some point.
Mix and brush in a coat of lay-up resin, then lay my CSM over the resin, and stipple the matt in place with a stumpy brush, add a little more resin here and there to ensure the matt is fully wetted out.
Then finally I consolidate the CSM with the resin by using a washer roller. The last part is often overlooked, but is important IMO.
Using the lost foam method, I would put a layer of fibreglass tissue over the CSM, before consolidating with the roller. Then when this has all cured, I would key up the resin and brush on a thick coat of Topcoat. Topcoat is Gelcoat with a wax inhibitor added.
