Sand the work area with 180 grit paper and you can work the plastic filler right on top of the 2K. If you go two deep and hit metal, don't worry about it. Just put your filler on it and "git er dun".

I would use Evercoat Z-grip filler.

No better smell than that of fresh paint. I've been building and painting cars/trucks for 47 years. Not gonna stop now.
