When rolling DiamondFinish Clear, it is best to thin 20% with KBS #1 Thinner and possibly thin subsequent coats a little more to prevent surface tension between the coats. The roller marks will flow out nicely.
When rolling DiamondFinish Clear, apply thin, covering coats and do not overwork the roller as this can cause the DiamondFinish Clear to cure too quickly possibly leaving visible roller marks. It is best to roll an area with DiamondFinish Clear and move on immediately versus rolling an area over and over again. If you roll over an area over and over again forcing the solvents out, you run the risk of the roller marks not flowing out as well they are designed to flow out.
