The real deal, solvent based Guttas made from Gutta Percha or other natural rubber. For experienced silk painters, Guttas hold the line far better for the Serti Technique than any water based Resist. Colored ones are softer, with less hand, than the colored water based Resists. So, if they hold the line better, what are the drawbacks?
The hassle of dry cleaning to remove the clear ones, and finding a dry cleaner who will even do it.
The fumes, as they are solvent based. Work in a well ventilated area!
Gutta generally has around a 6 month shelf life, and the colored ones can be even less, which can be prolonged by storing in a cool dark place. Heat and light break it down and shorten the shelf life.
Because they are flammable and due to US federal fire regulations, Solvent Based Guttas can ONLY be shipped by UPS ground to the 48 mainland states. See our Water Based Resists for other options.
