Refinishing filler panels

[rkreigh]

Hi folks, my filler panels front and rear have the paint a bit cracked up and I was wondering the best way to strip the old paint off. I though about having them walnut shell blasted, as chemical stripping will probably ruin them and hand sanding them will take WAY too long.

I would also like the source for those fiberglass fillers I've seen, can't remember where to get them.

thanks for any advice!!!

There are some paint strippers available for use on urethane parts, but they are very weak. I used one such product on mine to get about 50-75% of the paint off but I still spent hours and hours wet sanding by hand to bring each filler all the way down..
