simple green is a good cleaner & marker's work ok to cover up the very small nick's but for the bad one's i just repaint the case,it's easy & will make the gear look like new.
if the scratches are real deep lightly sand first & wipe the case down with a damp rag,preheat your oven(yes oven)to 200 degrees & put the case in the hot oven for 10 minutes,remove the hot case & spray on as many coat's as will dry before your eye's changing direction with each coat,i get about 4 coat's on while it's still hot,let the case sit for about 2 hour's then your ready to put it back together
rustoluem makes a fantastic paint for doing this,it's called 'hammered finish' & it comes in a few different shades ranging from dark grey to coal black,the hammered finish will make it look like a pro painted it & by having the case hot when you paint it you wont get any run's or drip's plus the finish is baked on & hard as a rock & will not scratch easy or wear off with regular household cleaners.
try to figure out how to hang the case beforehand & have everything ready before you heat the case,i use a coat hanger & have it hung in advance in the garage then i put the hanger thru a screw hole,i also have a few extra can's of paint on hand incase the tip plug's on the one im spraying with.
