Guys &Gals,
I have used West Systems Epoxy and I use another Technique to get the job done faster.
I go to my local fabric store and purchase som polyester fabric. It looks like a silk scarf. Really fine weave to the cloth.
I apply the fiberglass cloth and squeegee the West System epoxy on using a "credit" card sized piece of flexible plastic. Starting from the center of the part and working out to the edges.
Here is the trick part: I then lay the polyester cloth over the WET epoxy and smooth it down with my squeegee. Be sure the polyester is overhanging the fiberglass/epoxy by at least one inch or so.
Let cure over night and carefully separate and peel the polyester cloth off of the fiberglass.
This will leave a surface with a "Million" tiny "Nails" of epoxy sticking straight up from the surface of your part. Use 220 grit Wet or Dry sandpaper and lightly scuff the "Nails " down.
In about 5 minites you are ready to prime.
If you want to vacuum bag you can add a layer of 1/8" felt and do both side at the same time.
The excess epoxy goes through the polyester cloth and since the polyester clothe will not stick to the epoxy it will peel off. Taking the excess epoxy with it
Try it, it works!
