RE: Want to do fiberglassing... what do I need?
If all you are trying to do is get an acceptable surface for painting you may want to investigate glassing with polyurethane.
This method has about 60% of the strength of a resin job, but only 1/2 of the weight. There are no fumes and it is very easy to sand. The final surface takes paint and looks as good as a resin job, however it is more suseptable to dings than a resin job, but a lot less than a regular film finish over balsa.
If you are interested PM me and I will send you a basic "How To" on glassing and another on painting with latex.
