Patrick. I boil parts in a barrel of water, dish soap, and sodium hydroxide solution. One gallon costs less than the stripper your using, and will do everything on a weasel that will fit in the barrel. For large parts I build a fire under the barrel. For small parts I use a GI immersion burner to boil the water. Takes about an hour. In the summer, parts left in the solution for a couple of days have the same results. Just hose them off afterwards and they’re spotless. Works on grease and paint. I used to spend thousands on paint stripper.
