Percy's hyperfiber kits
 

Has anyone used them? How easy are they to work with and can they be sanded and painted? I've got some fender panel/door gaps I need filling in and I hate messing with fiberglass. Looks like a great product.

I didn't know if they were still selling this product... I really like it. easy to use, and takes paint and filler well... you can treat it like fiberglass after cure... The best thing is that is UV cure and requires no mixing.... I've fabbed heater housings, headliner parts, and other cosmetic covers... I like it.
