im too tight to buy the proper shears lol

ive been using a mixture of glass weaves, for the main flat areas of the panels ive used 300gm tight twill weave (2x2 iirc) with a thin even layer of gelcoat (used a paint roller again as you get less on the panel than with a brush) with 450chop strand mat for the corners and edges of the panels where they need a bit of building up or to make them easy to handle (front of bonnet where you open it etc). usually thin gelcoat, two 300gm weave, 3mm foam core then either another 300gm weave or csm (weave looks nicer but not really necessary). tip with the foam core, dont take it to the edges of the panel, leave 2"-3" from the egdes and use csm instead.
i use csm a lot though, with foam core it makes a mega light and fair bit stiffer than the same equiv thickness of csm or weave and much easier to wet out and get into corners and round curves.
