What do you guys use for the wheel houses' undercoating? It's the last thing I have to do for my Handyman.
This. I used SEM spray in bedliner on the underside of one of my cars and it turned out great. The Sem product mixes in little cans that spray with a body shutz gun. There are other brands like that if you don't want the SEM. Spray in bedliner dries harder than the undercoat and I think it is easier to wash clean later if needed.Spray on bed liner, It comes in rattle cans as well as quarts & gallons.
