I'm getting started building the interior doors for my new home. The doors will be stain grade alder with a brown tint and (probably) finished with Target EM6000 WB lacquer. I will be shooting the finish with a Fuji MPX 30 gun. I did some test runs and have been happy with the results so far.
On the test boards I brushed on two thinned coats of Zinsser clear shellac and sanded with 320. (On the doors I'll be using Sealcoat.) I then sprayed several coats of EM6000 satin which I had tinted with some dark brown water base dye I had on hand. As I said, I was satisfied with the result, but I want to play around with the color a bit more. I bought four bottles of Transtint in 6000 amber and three shades of brown.
My question is will I have better luck using the Transtint in the Sealcoat, or should I add it to the EM6000? I plan to use several base coats of gloss, with a final coat of either satin or semigloss.
