I looked at there spec sheet as years ago i made an equivalent to 3000 called "Turbo clear" a 3:1 mix, the resin back then was new and state of art but over the years got left behind, so I stopped making it.
Reading their spec sheet sheet the Production clear (2100-1) kills the 3000 in every way from mils to buffing and life of clear from feedback I get.
I'm working on a clear to replace the Deltron 2000 a 30 minute buff clear that will last like production and universal clear from SPI.
One thing SPI will not do with any clear is use a lower grade resin, cut back on UV protection and lower solids too accomplish this as we have no bean counters here.
Just about ready to start having labels made but just a little more testing to be 100% sure, I have all my ducks in a perfect row!
