I’m dealing with rust in interior body seams – such as where the floor pan meets the kick panel area.
Removing the old body seam sealer is easy – it’s brittle and scrapes right off. The question is what to apply before Brushable Seam Sealer. Is Fast Etch enough, or do I need a coat of something like Rust Encapsulator first? Would Internal Frame Coating or Heavy Duty Anti Rust make sense?
