I usually put a few brush strokes of Polyester resin first. Just to give something for the fibreglass to hold on to. Then i "stipple" the remaining resin onto the fibreglass. But perhaps Proprelicators way is better..
That's what I meant, I guess I wasn't clear. Sorry.
First off, mix up your resin in small batches. Nothing is worse than having a can full of cured resin and you've only been able to use a small bit of itbefore it hardened.
And pre-cut your fiberglass mat or cloth into small squares (3"x3" or so) or strips, depending on the layout of whatever your fiberglassing. If you have large flat areas, your pieces can be bigger. But with something with a lot of contour, you'll want the smaller pieces.
You paint on a thin layer of resin in a small area (maximum of 6 square inches or so, especially as you're learning this process), take a
dry square of mat/cloth and lay it on top of the resin you just painted on, and "stipple" the mat/cloth
into the resin. "Stippling" just just sort of pouncing the mat down onto the resin with your stiff bristled brush instead of using a typical "painting" brush stroke (a brush stroke will do nothing but make a huge mess.) Keep stippling until you see that the mat/cloth is completely impregnated with the resin, flat against your surface, and there are no air bubbles. Then grab another dry piece and start right next to the one you just finished.
You have to work pretty fast, that's why it's best to mix up small batches at a time.
Finally, wear disposable rubber gloves AND DON'T SKIMP OUT ON YOUR RESPIRATOR! It is NOT enough just to work in a well-ventilated area if you are doing something as large as a helmet.
Good luck, and have fun!
