I used T-bird for years then the QC started to suffer so I switched to Crystal and it takes a beating very well. A new product by General Finishes called Enduro is testing well too and it's a water based finish. I like the General and the Crystal better than the T-Bird, they stay really clear, the epoxy yellows over time. I refinished a Blue Dymondwood handled bow once, it was 3 years old at the time and the customer just wanted to drop a few pounds, when I sent the blue bows out they were a really bright blue, this one was more of a green shade when I got it back due to the yellowing.
