Hi Steve,
yes some small ones. But nothing "swap" related.
I`ve just sandblasted the whole underneath of the car and got it sprayed from a friend.
Just to give an independent advice:
Never sandblast your car at home with a cheap 200 bugs sandblast tool!!!!!!!!!!!!!!!!!!!!!!
neither sandblast in home, nor with a 200 bugs sandblast tool!!!!!!!!!!!!!!!!!!!!
Don´t ask, simply belive it!!!!!!!!!!
onto the edges and still rusty parts i applied "brunox", it´s some kind of rust inhibitor and epoxy sealant. I got it recommended by restaurators and collectors. It´s expensive like liquid gold
Anyway, at the end a 2K primer was applied. (not in pictures).
