Our Story

StopLossBags® keep your fine finishes Fresher Longer by keeping the paint in and the oxygen out. Think of them as the painters answer to boxed wine. 

Original Touch-Up- Update 11-13-2025

"If you’re like me, you’ve had many cans of varnish degrade as you’ve used them. Progressively getting thicker and thicker, finally skinning over and ending up in the trash. I tried everything to preserve those top notch finishes and nothing worked. I knew there must be a better way. 

Welcome StopLossBags®, a simple and effective solution. A clear pouch formulated to prevent solvent loss and inhibit oxygen infiltration, the woodworkers answer to boxed wine. Dispense what you need, then squeeze out any air before tightening the cap. Now, it’s possible for you to pour out what you wish knowing the rest of your finish will retain its quality until you need it again. 

May StopLossBags® serve you well."

Hello,

As the owner of StopLossBags®, I'm passionate about transforming the way you store paint. I've been an engineer and entrepreneur for years, always looking for real solutions to everyday problems. That's why I continue to engineer new products – to help you use all the expensive finishes you buy, without the frustration of ruined paint, messy touch-up's, or cluttered closets.

I believe in creating products that make a genuine difference. When I'm not focused on the business, you'll usually find me enjoying time with my family, out on the water, or building "something" new in my workshop.

Customer Testimonials

“We use a marine varnish that performs beautifully and goes into gel form for no reason in the can. Only stop loss bags perserves this expense varnish until we are ready to use it. It has saved me $100’s that I dont have to waste on gelled varnish. If it can save epifanes it can save anything. Buy some bags stop wasting $$ time and product. Highly recommend them.”

— Kristin L., Pennsylvania
 

“Thanks. I love mine and concur with your findings. These bags make my life easier and much more efficient. It’s easy to dispense just the amount you need, when you need it, and be confident that the rest of the batch will remain usable into the future...Great product.”

— Duncan H., Maryland

“I received a few samples of your bags at my woodworking club meeting about a year or two ago and have been storing my proprietary oil/varnish mix in them with great results. I am able to mix more at a time and store for longer periods. This has been a huge improvement saving me both time and materials.”

— Greg M, California

“The blend I mix for DIY wipe-on poly wants to settle a bit, and all I have to do is kinda squeeze and knead the bag, and it restores the uniform color I want. I appreciate being able to do that. It’s much easier than stick-stirring, There’s no guess-work, and I get visual feedback ...Thanks again for a great useful product for my small shop ... I’m gleefully recommending the StopLossBags® to anyone who’ll listen!”

— Edward P, Pennsylvania

“I received my order and I appreciate the thorough instructions and advice. Finally I’ll have a way to protect my investment in Sutherland Welles products. I’ve literally have thrown out gallons of gelled finishes over the past 25 years.”

— Bob B., New York

"Conclusion: the StopLossBags® keep air out as good as PET, or really close to it. And it’s much easier to take out the air after pouring part of its content. PETs can be squeezed only up to a point. (on using our product to keep photographic darkroom developers)"

— Mihai T., Romania

"Your product is outstanding."

— Michael L., Indiana

"I have been using your bags to store a hardwax/oil solution which skins over quickly. So far no loss of product with your bags."

— Brian B., Australia

Editor’s Review: Storage Bag Keeps Finishes Fresh

Many woodworkers know this story. You buy a can of finish, open it, and use it for the first time. When you’re done, you close up the canister and put it on a shelf. You use it off and on during the year, but there comes a time when you open the container and the finish is no longer usable because it has oxidized, thickened, or skinned over. I’ve thrown out plenty of half-filled cans of finish because of this. Well, not any more...      READ ARTICLE

StopLossBags®: A Better Package Design Solution for Wood Finishes.

In our daily lives, we live with such lousy package design solutions. A tube is a terrible way to store toothpaste, and when was the last time you got the last drop out of a bottle of lotion or shampoo? In addition to the user experience issues, there's the sheer wastefulness of plastic bottles that we use once and then throw in the recycling, still caked with residue. And when it comes to storing wood finishes, an even worse package design than bottles is cans... n the There's got to be a better way! mindset I dug around and found a company called Finishing Solutions, which makes a product called StopLossBags®...      READ ARTICLE
