no way to know ahead of time but wishing you knew then what you know now is a national past time lol.I said that in post 107. but I didn't know the bondo was oil saturated until I sanded the paint off. why would I blast off all the body filler and have to redo it if I didn't know it was full of oil?
not a serious comment in the first place.
most all of the old mills are saturated with oil and blasting or a needle file are the only good solutions, stripers tend to get stuck in the casting and cause issues with the new paint.
I have some experience with the same issue on cars with bondo and the use of silicon waxs. once a pin hole gets into the paint the wax soaks in and is insidious.
