hole in my 71 squareback where the front drivers side wheel well meets the body / pan. directly opposite the floor heat vent. it seems more 'body' than 'pan'. curves under, not flat. im not a welder. how to go about this? sheet metal, silicone and rivets? what to undercoat with?
the hole: a gnarly, no particular shape but about maybe 2" x 3" ? seems like it needs to be grinded into something workable (i.e. a more 'flush' surface) ..fiberglass maybe? ..
