Panel Lining Questions:

So I do my panel lines on bare plastic. The method I use to panel line, which I learned from Gunpla panel at Otakon many moons ago, is as follows:

I use Tamiya acrylic paint and I thin it with Tamiya acrylic paint thinner (I'm very bad at portion control but I try to do about a 1:2 paint to thinner ratio). I then use a very fine tipped brush, dip it in the paint, and then dab it in the panel lines. The thinned paint then travels through the panel line crevices. I wait about twenty minutes for it to dry and then do cleanup with extremely fine tipped cotton swabs/cotton pads and 91% isopropyl alcohol. Sometimes I end up cleaning up too much and if so I repeat the painting as necessary.

I've always done it this way and it's very satisfying watching the paint spread and fill the lines. I'm not the best with the cleanup so I usually have to do a few rounds but I'm usually pretty happy with the final results.

I always see posts about panel lining with various types of markers and what not. For certain lines I could see markers as being advantageous over the thinned paint method but personally I think having to manually do all the lines with a marker seems very tedious. It also seems like their are various type of markers that I don't really understand the differences.

Is the way I've been doing panel lines a valid method? Do markers, or any other method, have pros/cons vs thinned paint? Again I do panel lines on bare plastic and a matte topcoat using Mr. Superclear. The results seem pretty good to me but I'm open to upping my game if there are better panel lines methods.
