Spackle instead of bondo on top of fiberglass???

I wouldn't try using the spackle. I had the same bright idea with my kicks as Bondo is the sucky. I used some spackle, sprayed some 3M Super 90 and my vinyl won't stick and is making a gummy residue where the spackle was. Just get the Evercoat Rage and be done. Mark
