    Okay, here's the scoop. I shave the side trim on my Honda CRX and had to fix a couple rust holes.

    IT KEEPS CRACKING!!!

    The car has not moved yet, it still has an engine swap going on. I've heard that if you build up too much body filler at one time, it cracks. I learned my lesson and now only apply in thin layers.

    How do I fix the cracks now? Do I just grind a 1/2" trench down the cracks down to the metal and slowly build up layers of body filler? Would that work?

    filler should be no more than 1/16 maybe 1/8 thick work the metal to a flat then use the bond to fill the minor dents. If you filler is 1/2 tick then its an issue you need to adress. For blening panel you kitty hair it can be used in thick coats, and will not crack. It is choped up fiberglass mixed with filler.
    Also if the metal is not preped properly filler will crack and fall off

    I'll get right on that. Can I borrow $500 and never repay you?

    Thanks for all the help guys! I'll try the Fiber-bondo on the side trim pieces then finalize with a coat of body filler.

    Would regular mineral spirits and a swab of aircraft thinner work for metal prep to promote adhesion?
