Same as I did for the fiberglass..
Simply pass it with a paintbrush first on the foam with the epoxy, then put the kevlar/fiberglass, let it soak in a couple minutes, thne pass it again with a brush of epoxy. After that I use a transparant plastic sheet and cover it, and I press it to squeeze out the excess epoxy, then soak it up with clothe.
I leave the plastic on, and I put it in my kitchen oven at 40-50C ( a part at a time ;-) 20 min per side) as to heat up the resin which makes it extra hard. Then leave it rest for 24 hours. Then strip off the plastic and then finished... the shave it...
Please ALL USE GLOVES when working with Kevlar as it causes cancer, and please do NOT polish it with a sander, as the dust particles could reach your lungs.
