If at all. The guy who owned my z before me used fiberglass (which is better than bondo) and now I will have to replace several panels due to rust damage.

You do not want to use Bondo on a 30 year old car. Bondo absorbs moisture and will turn your prize int o a rust bucket.

Go to www.eastwood.com and search body filler for better alternatives.

That said, bondo is rather easy to work with if you have a steady hand and some artistic talent. Sand and prep the dented areas. use body hammers/dollies to get as much of the dent out as possible. Then apply the bondo in several layers. Use a straight edge to determine the deepest part of the dent and start the first layer there. Apply your layers carefully and you won't have much sanding to do afterwards.

Very important!!! Wear a respirator. Bondo dust will kill you!

I have to agree with Enrique. I've been using bondo and fiberglass, and even lead, for the last 20 years. The key is in the preparation. Make sure the metal is clean and has some good scratches, 36 grit, before applying.
