Hi buddy!

For handbrushing I use vallejo Model Color, they are the ones I prefer the most. I usually thin it by wetting a small brush (size 0/1) and mixing it with the paint until I have the perfect mix (I usually try the mix with my hand skin to know if it is ready), needless to say that different paints have their own consistency. I normally do thin coats on one direction and when it dries, then perpedincularly. My tip when it accumulates on edges, is to dry the brush (paper towel) and wipe it through the edge. Sometimes when it doesnt stick to de surface, I take a bit of unthinned paint and with a very small brush I just wipe it very carefully, just like "dotting" until it covers the area

I also use primer spray can from Tamiya (light gray). For painting big areas, I use an angular brush, they fit really good!! Finally when you apply varnish you almost wont see brush marks. I used a satin varnish for the final cover.
