I bought five connected fold down theater chairs. Looks like 50's.
They are made of laminated wood, similar to plywood, and are curved.
The type like they used to make curved barstools and chairs and desks
out of. They are in decent shape, but are separating a little here and
there. What would I use to get them back to original. I would imagine
glue inserted in the cracks and held together with a clamp of wood
pieces band saw cut to fit the contour. Which type of glue:

And there is black paint, covering up a nice pine color underneath. It
looks like latex, as it is coming off in flat flakes about an inch
square. What would be the best way of getting off the wood without
introducing much water, or something that may cause it to delaminate or
cause further damage. Thanks.
