Can you make pre cat urethane non transparent black? I want a shiny black extremely durable finish that will show the open grain pattern , but not transparent that it show the wood grain patterns. to specify i want to see the pores but not the wood patterns. currently my project has been dyed with Behlens jet black NGR dye, then cleared with GF pre cat urethane. in normal lighting it looks likes has a really rich black lacquered look. when direct light hits it , the variance in the heart and sap wood reflects the light back differently making the finish look like the heart wood is black and the sap wood portions milky. i didnt fill the pores because i like the look of unfilled walnut, but wanted to hide the wood patterns. i have tried a few coats of trans tinted urethane but it is still transparent enough that you can see the patterns in direct light. i only mixed 5 drops in about 500 cc (half the large gravity feed tank on hvlp). Can you put enough in the finish to make it non transparent? any suggestions ? while in thought, i do not want to sand the finish down because im afraid it will level out the pores. i have a sanding sealer coat and three top coats. i am really looking for a fix (scuff and go over the top), but am humble enough to hear all suggestions. thanks

Yes. Either mix in more dye or spray more coats. You would want to select the former rather than the latter…too many coats will cover over the pores. 5 drops of dye in that much finish is a little thin.

where would be a good place to start? 10 drops , 15 drops ? Can i use india ink ? would it be better than trans tint? the black Trans tint has a purplish color to it to it. i want true jet black.

India ink is a very good choice as stated, wear rubber gloves when handling it or your fingers may change color also. You can order pre-mixed black lacquor also in both water base and standard lacquor.
