I used Unlimited stuff on my Pinto and it was the nastiest fiberglass I've ever seen. It took a lot of body work to get it ready for paint. I thought there was a thread on RJ about them but I can't seem to find it right now. There is a thread on another site if you want to check it out here.

I used Glasstek on my Probe and couldn't be happier. Some light sanding and a little primer and it was ready for paint. Their website shows the Vega stuff.
