Removing top layer of bottom paint
A couple of years ago the previous owner had the whole bottom done with black Trinidad SR. They just added a couple of coats to what was there already.
The problem now seems to be that the top black paint layer is flaking off in places, and has the odd bubble in it. Not to be confused with true blisters, it's water getting under the badly-adhered top layer.
I can only assume that the bottom wasn't properly prepared before painting.
Soda blasting 20 layers of paint off seems a bit drastic. Is there a process, apart from sanding which isn't allowed, which can just remove the top layer and get down to sound paint? Can they soda blast lightly?
