Just curious to see if anybody has ever tried glassbeading or sandblasting fiberglass? I have some fiberglass fenders that are cracked, and there is a lot of dirt in the cracks or between the splits. I was going to try and clean most of dirt out and see if I can epoxy most of the cracks back together, but wasn't sure what the best way of cleaning the dirt might be. I would think that sandblasting would be a little too harsh on the fiberglass, but what about glassbeading them? Since most glassbeading cabinets don't have the higher pressure, I thought it might be a little bit more wiser to use it. I guess sandblasting could work if I turned the pressure down on the tank too, but I'm still just a little scared of using this route.
I guess I could just cut out most of the cracks, and just build everything back up with new fiberglass, but I was hoping for an easier fix. Any suggestions?
