Are the Stop Loss Bags a throw away item after one use, or, can they be flushed with the appropriate solvent and reused? Thanks.
That's what I do, as well as clean up the spout and cap. I fill them with mw poly.Did you splash some mineral spirits in it and empty, prior to refilling with the Watco?
I used to get big toothpaste-like tubes at the camping store for stuff like peanut butter. They opened at the bottom so you could fill them and you slid a split tube over the doubled-up end to seal them. I imagine they would work fine for a thick finish. They come in a variety of sizes, here's an example https://www.rei.com/product/696007/coghlans-squeeze-tubes-package-of-2The two finishes I use these days are very high viscosity, think pudding. The idea of the stop loss bag is appealing, but I wonder if one could fill the bag with something pudding thick?
