In the middle of prepping my bus for spraying and I'm looking for any tips on flatting behind the rear side air vents any good ideas out there?
I had to clean a set after an engine fire. I found a bent toothbrush taped to a bent tent peg worked ok. Maybe something similar with a small wood block on the end and sandpaper attached to the wood?
I purchased a grit blasting gun and some media. Came up a treat, but took ages to get rid of all the grit!
