I've used both, Speedway does make their own, but you get what you pay for...Resin rich, heavy and wavy..You can do bodywork on them, but the waves will come back. Wescott's uses a better resin, and hand lays them so they are not overly resin rich... (not that you can't make decent parts with a chopper gun, but most companies don't take the time.)
my signature lines...not really directed at anyone in particular..
BE different....ACT normal.
No one is completely useless..They can always be used as a bad example
