what is the best product to use to repair a crack in 99 dually fender

 

I don't if this is the right way or the best way.I had a couple of tears also.I fiberglassed the tear from the back and it seems to be ok so far.

 

I was going to suggest fiberglass as well. Just make sure to grind area free of paint and v the crack. Make up your fiberglass and resin how ever you prefer and apply. Once tried and sanded it should be good! Could also do the inside of the crack too if you really wanted to, but that is a bit more work.

 

drill both ends of the crack as well to stop the crack from spreading.

 

Make sure you glass it inside and out or it will crack back thru...
