I have been reading and studying every build thread on this site itching to get to the point of building back instead of tearing out. Hopefully soon.
There are scraper attachments for reciprocating saws that I just discovered this week. I think they would work well on this. Spyder brand is what I got. I got a 2,4,6" set to try to get the spray on glue with bits of insulation stuck in it off my ceiling and a bit in the middle of the sidewalk sections. There are some areas under it with surface rust, or I would have just spray foamed over it. The 4" was impossible for me to control but the 2" works ok on the ceiling and pretty well on the side walls but I have to be careful around the things that look like nail heads on the inside of my side wall skins. I'm sure they aren't nails, I'm guessing the other side of rivets for the rub rails and I'm sure I'm not supposed to remove them.
On the floor for the rubber I'd bet the 4" or even 6" might work, especially if you have a reciprocating saw that doesn't vibrate as much as my cheap ass one from HF.
Should I just spray foam over it and not worry about a bit of surface rust and make sure that my roof really is well sealed? I bought it with the roof already (in theory) caulked, primed, painted with elastomeric and a coat of flexi coat. But I get a bit of water in the bus when it rains still in 2 places but I can't figure out where it's coming from!
My Dremel multi max doesn't have enough power to do more than a small area of the spray glue removal without overheating (it's only 1.2 amps!! I've had it for at least 5 years and I knew it was a lot slower than some, but I didn't realize it was essentially only for light projects). I have a 5 amp Rockwell on the way because it had significantly better reviews than the Dremel Multi max but is supposed to use all the attachments I have for that one AND not require a tool to change the attachments. That will be a nice upgrade for the tool box.
I also killed my angle grinder already and need a beefier one of those as well. I don't want one that is TOO heavy so I am looking at the 7amp range ones instead of the 11 amp ones that are quite expensive and the 4.3 ones which is what I had before and killed.
I need to find my large 4" razor blade scraper intended for wall paper removal because I think that may work even better than the 2" utility scraper I tried yesterday.
