@Mike – Streaks or brush strokes? If brush strokes, then thin it a little more before application. Same thing with streaks when padding it…get it thinner. Other problems, like blushing, can also happen whereas the DNA might be old or contaminated with water OR it might be flashing off too quickly OR have a contaminate on the surface OR too much moisture on the wood. Regardless, whatever the issue, additional, better applied coats should eliminate the problem OR wiping it back with some DNA. When you wipe it back, stop at the point where you feel the surface tug at you…at that point, the stickiness will screw things up. When padding, whether with adding shellac or wiping it back, a few drops of mineral oil (it’s clear) will lubricate it for you. I typically just use a make-up sponge and work it quickly before the shellac gets sticky.

Regardless, using a fine cloth or sponge in conjunction with DNA should smooth things out pretty well, but I normally will use a fine 3M pad after every other coat (or so) when I feel there is something I need to level or smooth. When my shellac is tinted with dye, there can be little drips and runs that become somewhat obvious and I rub them back in that way.

But avoid doing too much at once. Work quickly and resist the temptation to put a ton of shellac on it in one session. Cover everything, and then stop. Wait to dry, then repeat. In our climate, it will often be ready for a new coat in 5 or 10 minutes anyway.

Oh, BTW, I normally spray shellac…the only time I wipe is when tinting it with a dye and needing to control where it goes…or when I have something else in the spray gun and am too lazy to switch it out. :)
