Of course I'm biased so take this with a grain of salt but I'm doing some personal tests on the New water based "Cason's Crystal Clear" CP from Cason Custom Rod Finishes. 1st pic is after 2 coats and 2nd pic after 4 coats. As you can see there is absolutely NO hazing or visable acrylic crystals present common to other CP products in either pic. alsmost looks like bare thread!
3rd pic is a couple mixing cups that have a thick bottom of the CP that I let evaporate completey leaving only the acrylic solids behind and again NO hazing and still absolutely crystal clear.
You can get this stuff at FTU, MudHole, acidrod.com, and Swampland!
