I have been using GAMVAR lately. It can be applied rather soon after your painting is finished. Soon, as in a week or two. So far, it has worked fine for me. I decided to try it after hearing good reports about being able to use it a couple of week after my paint was touch dry. (I paint rather thin, though.) I paint portraits from all around the U.S. I like to send them on as soon as I can. GAMVAR does that. NO . . . I'm not an employee nor do I own stock.

Im getting Gamvar I came to this conclusion too after a lot of research online but your post gives me confidence I am heading in the right direction. Thank you again ... Mark
