    Hi All

    I like the theory of Bondo over foam, etc - But I can NEVER get it to work right - It always hardens too fast, wont sand well (too hard) etc -

    Is there a trick to using it? Is Bondo-glass easier to use (The Bondo fiberglass)

    Any help would be great! Thank you!

    never heard of doing that! So do you add the hardener to the "rondo" that the bondo uses after its mixed? Or do you add the hardener to the bondo before mixing?

    you mix bondo and resin well first, then you use the harderner.

    If memory serves me well...

    You want to use the resin catalyst as opposed to the bondo hardener for the mixture.

    Double check that just in case I am mistaken

    you can cover the styrofoam with aluminumfoil before useing the rondo/bondo... Also there is another typ of foam that some people use (pink foam?) that do not melt when resin is applyed.
