To answer a couple of your questions , I think that pink stuff is “Bondo”, pretty common fix back when. It actually looks like it held up well.
I attached a picture of the bags I use when I steam. Steaming in a bag works really well, and you’re not stuck with the big box afterwards. Steaming those inwales can be done right on the canoe with a bag,
I liked stripping with Total Boat stripper, Just seemed to work better than anything else I tried.
Now, don’t get me wrong, to each his own I guess, but 15 ribs is a lot of ribs to replace unless the canoe had some sentimental value or was unique I would pass on this project.
WC canoes have really dropped down in “asking” prices lately from what I see on Marketplace. Right now there are two canoes, a 16’ Old Town and a 16’ Chestnut for less than $800 in my viewing area here in Maine, both in great condition maybe only needing some paint and varnish. You will be spending a lot more than $800 on your canoe imho.
But, I’m old and done with big projects. Good luck.
