Grain filler question

[Mike Wilkins]

Does this stuff have an expiration date, or does it ever 'go bad'. I have a can that has been sitting around for about 15 years and wondering if it is OK to use. Or just get off my cheap rear end and buy another can. Thanks.

Regardless of the theoretical lifespan, I'd try it on some scrap first!

There are lots of different types of grain filler. What type do you have?

If it were me, I would discard it and buy new. The finish is no place to be frugal.
