I use the same product Tim talks of in his video, same formula as his new distress glaze. He's so right it really goes a long way, I purchased an extra container when I discovered it would no longer be made and still haven't had to open it. I find it indispensable when stamping on envelopes to be mailed, and anytime I want to seal water based ink or paint. I even use it on my professional watercolor paint projects. Although it can be used as a resist, I haven't used it for this purpose. I highly recommend this product!
I love using this as a resist medium (Search on YouTube for Distress Glaze Resist) AND for sealing my ink smooshing when I use alcohol ink paper (smooshing with Oxides OR alcohol ink). It seals beautifully and then it makes the layers of color just magically pop. WOWWEE!!
Apply distress glaze to your distress oxide projects & watch every layer instantly come to the surface making it very vibrant & smooth. It seals in your projects making them waterproof. Only use a little, it goes a long way. This stuff is amazing & not just for oxides either. I sealed my pearl ex & perfect pearls projects with the glaze & it worked perfectly.
