PSA: Tried a cheap filler from the parts house vs. the good stuff on a quarter panel
The cheap stuff shrank and cracked after a week, but the Evercoat Rage Gold I usually buy laid down smooth and feathered perfectly. Anyone have a go-to filler that holds up in humid weather?

Seriously? It's just body filler, not a structural weld. I've slapped the cheap stuff on a truck bed corner and it's still fine two years later. Maybe prep was off or it got mixed wrong. Humidity messes with everything, but a good primer seal should lock it down.

That cheap stuff has a lot more talc than resin, so it soaks up moisture like a sponge. A proper two-part filler won't do that even without perfect primer.

Exactly, it's all in the prep and the mix. I used that cheap one-part filler on a fender once and it bubbled in six months. Switched to a decent two-part with a wax-free glaze, sealed it with epoxy primer, and that repair is still solid five years later. The cheap stuff is just false economy.
