This might sound like a bit of a dead-end question but I'll try anyway.
We are trying to take the floor out of our trailer prior to painting. It is a marine-ply floor with spray rubber on top.
We have discovered that it is screwed into box sections and the screws have been covered by extra spray rubber layers put on by the previous owner.
Anyone have an idea how we can get these screws out of the box without wrecking anything? I would really like to keep the floor in one piece and of course there is nothing wrong the with box so I don't want to hurt that either.
