The only reason i ask is because you really should have glassed it, bondo will crack when flexed a tiny amount.
i thought of this as well and tested my mixes, when i used slightly less hardener it dried more hard/rubbery...used that mix and i tested that already and flexed it b4 paint with no issues and on top of that the truck bed coating dries to a plastic hardness
