- This would be a lot easier with a hot wire to cut the foam. A razor is not very easy to get a nice cut with — if I use a hot wire I suspect there will be a lot less sanding and shaping work to do.
- It’s harder than it looks and I think it’ll be a little wonky… meaning I may have a fair amount of second-phase shaping using spray insulation or something like that!
Watch out for spray insulation.
The stuff I worked with was not closed cell (greatstuff) and it soaked water up like a sponge. My project almost sank. I ended up sealing all the open pores with epoxy.
