For those who've ever stripped out the interior, taken down the walls, scraped away old foam insulation to inspect for leaks, and wanted to start clean; I'm sure you know how hard it is to clean down into the gaps where floor meets wall. Even the air compressor and screwdriver / scraper doesn't get all the years of dirt accumulation and crap; and i didn't want to just spray new foam down on top of dirt... I want to properly seal those gaps with sealant first! Well, today i found a solution: Power-washer! Borrowed a friend's... put on googles and a raincoat, put it on the highest setting and yee haaa! Worked fantastic... had to be careful about remaining wiring, but wow, what a result: Ceiling, walls, floor... old bits of foam and dirt stuck between the ribs just washed away, down the drain; and now i can say we've got a clean slate to work with.
Followed up with the air compressor and shop wet/dry vac... Gotta make sure everything is properly dry before we seal it all up, of course. I'm thinking self leveling sealant for the nooks and crannies between floor and walls and roof. Also considering a quick coat of duct sealant, spreading it on the walls like paint; to seal away the multicolored remnants that remain,.. the old foam orange, the zinc chromate green and the bare aluminum. At least i'll test it on one wall and see how it works to later to affix the foil-back foam insulation (once dried), using 3M 777 spray adhesive on top of the dried duct sealant. Or, maybe just spread the duct sealant on the walls and then let it BE the adhesive?
Point is, it might be a little while before we seal everything up with the luan headliner, etc.. still debating what we're gonna use, and the color scheme; and so some bare walls might be exposed for several weeks while we make sure we've got all the wiring taken care of, etc. Might as well add this extra layer to have that "clean slate" to work from:

We're going to start on this job tomorrow, so if anybody thinks i'm overlooking something, or has some better products to suggest, please let me know, soon, thanks!
Also, we're probably not going to get around to doing the flooring until the spring or summer, so i'm thinking of just putting a coat of paint on it for now. Even the power-washing couldn't remove 38 years of ground-in grime, dirt, bits of old paint.. Any suggestions on minor floor prep products or type of paint? i'm 90% sure we'll be putting a hardwood or vinyl floor on top eventually, but we're gonna live in this coach fairly full time from mid January to April, so a quick coat of paint and then throw rugs on top would work for now.
As usual, i'd surely appreciate the feedback from those who've done this job before, thanks much!
