Fleece

You use fleece because it is stretchy so it will take curves. Fibreglass mat needs to be supported when wetted to no chance of pulling off a stretch with it.
Depending on the size and intricacy of the stretch I will use:
1) Grille cloth - great stretch, very thin so always needs to be backed with mat.
2) Light fleece - very good stretch and way cheaper than grille cloth. I always add mat after for strength.
3) Heavy Polar Fleece - yep just like a fall jacket or liner to a 3way parka. Decent stretch but I don't do anyhting smaller than KPs with it. Can go without backing for small to moderate spans. I'll make a resin/chop fibre slush to back it up or a single layer of mat.
4) Trunk liner - ok stretch but can give you a well supported span when wet and can be relatively strong for medium spans depending on what it is doing. Cheapest/yard of all of them too so useful for full trunk stretches and such.

Seahag..
Start by cutting your mat into smaller pieces.. some 3"X6", some 3"X3", some 2"x4" etc.. oops edit.. your doing the inside of the kicks.. in that case 1"x3" peices.. [img]smile.gif[/img]
sometimes it is easier to place the dry mat where you want, then brush the resin onto it, soaking it after. Sometimes its easier pre-soaking the mat, all depends on what your doing.

I buy chopped or milled fibres from the supply house - can make your own with scissors, fibreglass mat, and some time. Think 1"x1/2" pieces. Add them to resin until you get a mix that is thick but still flows well. Pour a bunch into the KP through the speaker hole and slush it around inside all over so it coats all surfaces but especially the fleece. Keep rotating the KP until the glass mix gels up.
When dry it is surprisingly strong [img]graemlins/thumb.gif[/img]
