seems to me that the advertised method here is crayon wax.I used testors model paint.its acrylic.whatever.but it has not come off at all via solvents.even soaking.how,I took something small , paint brush , toothpic needle, something.and covered completely the "roll mark" only one area at a time maybe 3/4 to an inch because this stuff set up and was harder to do the next step.after covering, I got a rag and wiped it off with my finger (your method may vary) and used the rag to wipe that.then once all areas were done whatever colors, I waited 24hrs for it to dry good(it came out easy if I did'nt)then I used testors thinner (solvent) and q-tip wiped off the smear.don't get it too wet when doing this and don't do it very long,it pulls the paint out.after a few more days it is dried very good and if you want/need to touch up it is easily done.I did my HKs this way and they look good and so far after many soaking/cleanings it is still looking like day 1.
