Doing the doors. Getting regulators etc out and down to the pesky set screw on the lock on the first one. Noticed how bad the inside of the doors are rusted and dirty. Any best practices on getting them cleaned? My first thought was flush a half dozen times with krud kutter, scrub what I can reach. power wash it out. Reach as much area as poss with some rust reformer with those long nozzels for frame insides ? ? seems like a real pain in the ass. lol. Watched the vid of dudes 41 plymouth doing his doors. they looked impossibly clean. lol
