you can put an matting base additive in 2k and clear coat if you want. it works well. most paint companies have this product. PPG have it etc. you can get the paint shop to add it to your paint, or buy it your self and have a play with it. spray some test panels first to get your satin, or matt finish you are after. only paint over 800 wet or 500 with sander. matt finish show up everything, dents, sanding marks, it sounds weird but its true!
