Duramix 40/40

Not very well. Duramix is a plastic adhesive. Though I have never tried doing it, I don't think it would work well. What are you looking to accomplish? DXAV

Saint,     The way fiberglass bonds to another piece of fiberglass is because the way the resin reacts with the fiberglass material. The reason it bonds to MDF is because the MDF is pourous. I am not sure the fiberglass would stick well to ABS plastic. Roughing up the areas you want bonded with low grit sandpaper should help the bonding process. This may be difficult if you are trying to bond just an outer edge of some ABS. I know fiberglass is used in the primary stages of fiberglassing dash pieces, and the final stages are done with plastic adhesives and fillers. Bondo will curl after several months if applied to plastics. DXAV

Sorry for the runaround. I highly doubt it, Saint. The duramix activates chemically with plastics. I don't think fiberglass share those same properties. Do you have some pics you could post so we can get an idea of what you really want to do? You could take the plastic and drill small holes along the edge to be glassed. Then glass over the edge, where the holes will seap fiberglass to the back side, cure then bond tightly. You would still need to rough the sides of the ABS with sandpaper. Glassing to the plastic may be easier than trying to bond 2 separate pieces together. DXAV
