Technical Home made undercoating

2 years later and it is still holding fine, no noticable rock chips, flaking or peeling. I have took my truck through the woods and had limbs run up under the truck and the only place ive noticed it coming off is the under side of the axles. I am fixing to mix some with white paint in an attempt to get a no slip light gray color to spray in the bottom of my aluminum boat.

 

always good to get an update, thanks.
