Counter Culture DIYClear Quick Coat Sealer for Resin Art, 4 oz Bottle Epoxy Supplies for Coating & Casting, Tumblers, Keychains, Jewelry, Outdoor Sign Waterproofing, No VOC (4 oz)

I use this to seal vinal designs on my tumblers before I epoxy them. I have had excellent results in the vinal not coming up because of epoxy getting underneath the design.

I won't epoxy over glitter without it. I've used it on fabric, over adhered glitter, and over cardstock. It helps me achieve a smooth finish without using so many coats of epoxy.

Fast Shipping, great quality worth the price.

Pay attention to the ounces that you order because I accidentally ordered the 4 oz which took a long time to get here and it's itty bitty.

Brings out colors beautifully, when first applied. I keep getting opaque streaks after it dries, but that’s probably operator error.

I recentky started using this product and I will never use another sealer. This dries fast and it doesn't take much to seal your projects. I use these on epoxy tumblers. I use this to seal my glitter before applying epoxy and also my decals. Great stuff!

Worked great for sealing vinyl, and even hot glue onto a tumbler

I had heard of this product being a great sealer for cup tumbler projects. It is definitely a product that I will order again. It works and seals great, and works well with epoxy.
