How old is that Tech sheet? The most resent one shows the sealer being mixed at 3:1:2.
I donít know why there are a lot of people beating me with the guide coat since I said that Iíve been using a light colored lacquer for that. And it also looks to me that I was done with that part as far as using it to block out the high ands low spots. Other than the scratches and the concerns about the URO, I didnít have a problem.
