I would like to paint the inner face of my outer sills prior to them being fitted.
They are Heritage sills and there are no spider tracks or rust present.
Presumably, I can just rough up the e coating with something like a scotchbrite pad.
Do I then spray the entire inner sill with weld thru primer or just the edges that will be welded then the rest of the inner sill with ordinary primer then apply top coat?
I've seen Sonikk4's thread about installing inner and outer sills and saw that he'd drilled the holes for plug welding first then painted.
How about drilling holes on the outer sill, before fitting, for future cavity wax injection. I know there are the 2 square holes on the inner sill but also adding holes adjacent to possible rust spots like the internal slinging brackets a either end and the jacking point in the middle then capping them off with plastic bungs?
Any other tips?
Regards
Mike.
