After 30 years we've had to redevelop the Resist due to changing raw materials. It's a long and slow process with many formulas failing with the newest materials
UPDATE 2024 - we FINALLY have a viable BETA test of a Resist that performs as well as the past one. We have free samples for customers to test as we await final shelf life testing. Just add a BETA test to your cart. No charge (shipping is extra though).
