I'm interested in using it to dye some plastics. I want to mix it in the correct solvent for the dye job.** A: I can tell you that it is a oil base I diluted it with some lacquer thinner. I will tell you that I would be very careful ordering from this vendor. The first one came with a broken lid. They said that they would send another and they did but it had the same problem. On top of that long after I inquired about it they wanted the broken one back and I had thrown it away because there was noting left it was all over the packaging. So I ended up paying for both. ## Customer Reviews ### ⭐ 1.0 out of 5 stars Not as expected *by L***N on Reviewed in the United States on July 13, 2019* This stuff drys out super fast and was leaking when I got it --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/135273360-invisible-permanent-uv-ink-fluorescent-ink-visible-at-black-light](https://www.desertcart.co.uk/products/135273360-invisible-permanent-uv-ink-fluorescent-ink-visible-at-black-light) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-06*
