I didn't know either.. I have only repaired a few cracks in yj tops.. But I used what was available at the local Home Depot as that is what I keep around the shop at all times.
I just clean the area. Sand a little. And apply resin and cloth as needed. Then I sand it to suit my needs and paint with whatever MIGHT almost match the color..costs bout twenty bucks and I have never had one to recrack or otherwise fail.
