IT's H20 they are on predators web site...if you have someone else dip your bow ask them if it is a screen type dip some companys use a rubber like coating that you don't want on your limbs..
another company that does a great job also {but not lic for predator} is tar-jac they did my silvertip with a checkered grip I shot it for about 6 years an the screen never even wore off the checkered points this stuff is very tuff..you should be able to get it done with insurance and shipping for $150.00 or less..
