JASCO Liquid Mask & Peel, Liquid Masking Tape, 1 Quart

Great product. I initially put it in too thin which made it hard to relive but painting a thicker application fixed that issue. Get a glass scraper as well for best results

This helped our painting go faster, and peeled off with ease! Just get it!

This is the stuff to use for painting window sash. Forget using tape, paint will crawl under tape and may pull paint off. anyway. Just paint this on the glass with a narrow brush, putting on a thick layer about an inch wide. It's okay to get some on the wooden mullions or sash bars. After you prime and paint the sash and it is dry, use a utility knife to cut along the side of the wood, at a right angle to the glass, getting into the corners. Then, using a razor blade scraper, peel off the masking. Most will come off in large sheets, but you will need the blade to lift it in some areas and out of the corners. The result is a perfect, crisp paint line at the glass.

Product works well just ensure you use a thick layer, or it is difficult to remove.

Pay no attention to reviews of less than 5 stars. This product works. Just follow the easy instructions. A caveman can do it. I painted two 15 window French doors with perfect results. Price is well worth the time you will save.

Junk. It dried clear. Waste of money. It is hot and humid & is white going on but thin and dried clear. I do not recommend.

I thought I’d try this product and I am thrilled! Saves me so much time and prevents leaks when I’m painting.

This product is neat no doubt, however you have to put a solid amount of it on the window as well as completely cover of with paint in order for the most satisfying peel experience. Also this works better if you spray paint over it vs using brush. Overall i didn't notice much of a time saving for normal window applications, but can imagine more time savings of you have colonial or craftsman style windows.
