Just a quick post about a product I’m trying — I am not sponsored by these folks are anyone else.
I read about StopLossBags in The Family Handyman magazine and wanted to try them since I’ve had to throw away a considerable amount of varnish and polyurethane over the years. Storing polyurethane and varnish is a matter of protecting it from air and these bags look like they will solve that issue.
I used a small funnel to store about half a quart of leftover oil-based polyurethane and was able to easily push the product up to the top of the bag forcing all the air out before closing the bag. The bags arrive with lots of directions and even plans for building a small stand to facilitate filling bags.
You can check their website here.
I will add an update later with how the finish is holding up.
