David,

I'd still be careful about the effect of the thinner on the frisket...

If you have a scrap surface with a similar finish, or even a scrap of glass to try on, by all means do so! (A glass surface is about the easiest to clean up with thinner and perhaps an X-Acto blade scraper...)

I tried a frisket material once that had all the applications claimed with all the products in the catalog at your link. I dodn't see anything that claimed compatibility with laquer or dope thinners. These are powerful solvents! The frisket I tried puckered, lifted, wrinkled and sucked dope under the frazzled edges. NOT a pretty sight.

A mess. Hope your projected material is better.

I've only glanced through some of the posts above... Has anyone mentioned low-tack shelf liner? Haven't tried that, but hear it is simpler than the masking I've built up on glass using a #11 blade to cut outlines.
