Hi Evro
My research reveals that Shellite has the same chemical formula as "naptha" which our American friends use liberally.
I've found that it's especially good for getting rid of the goo left after removing p/f Mylar etc.
Bunnys in WA do stock it. I've been using it effectively for ages and it works well even to clean cab decal dirt.
So far absolutely no damage caused.
Hope this helps.
Max
