I finally committed to fiberglass after months of driving around with ag plastic sheeting duct taped to Slambo's nose.
There's two layers of fiberglass cloth covered with multiple coats of resin underneath the primer, with minimal bondo at this point. I rattlecanned it to get a better look at the low spots and lumps.
Next up: trim the grille opening and inside the wheel wells.
With luck, I'll have a video done by next weekend.
More photos TK!
