Ospho and body putty

chuck machinist · Nov 15, 2020

I have prepared an Ospho solution sprayed on to a few non-
critical non-seen parts on a tractor. Should asphalt be brushed
or washed off after drying, so that I might apply a small
amount of body filler before prime and paint. CM

The Ospho solution should be washed off with water after the treatment and then dried. If you plan to use an epoxy primer I would do that first before using a body filler. Then when you get the surface level use epoxy primer again. If you are just going to use a alkyd primer you might as well do the body work first and then prime.

Thank you Steve. These few parts will not even be seen after the sheet metal goes on. I like to be thorough, but I will not be an al about those few pieces.CM
