I'm not sure!
I have recently tried to remove a very thick varnish from some door frames and have failed miserably. I used nitro-mors, this just took forever and i nearly passed out from the fumes. Then i tried a blow torch (not recommended) it had the same effects, producing a lot of evil fumes and gunging up my scraper.
If it is reasonably thin, Nitro-mors may work!
