Here is/was my Romanian bass post strip job. A friend and I used a heavy duty chemical paint stripper- I'll look about for the jug- Apply and leave sit for ten or fifteen minutes- "Better living through chemistry!"

The finish bubbled up and could be easily wiped off with a plastic scraper.
Definitely wear gloves!!! A respirator prolly wouldn't hurt either- we did the work outside and still used both.
Wipe down with what ever it says on the lable, prolly denatured alcohol.
It made all the difference in the world as far as tone and volume production- most folks that were familiar with it prior to the re-fin can't believe it is the same bass.
Good luck with your bass!
