what hardener for fiberglass?

[mikerallye]

Can you use the same hardener used for bondo in place of hardener intended for dyna glass fiberglass? It is the green stuff with strands in the can?

yes,you can, the color makes no difference, it's all same

Thanks for the info, been having the same spot keep bubbling after 6 months. Thought it may be hardener.

Sounds like your metal isn't clean before application of the mud.

dyna-glass filler is trash,especially if it's been sitting for a while, use Everglass
