rachtech like red loctite.
no the didn'y peen the base lugs usually the cross screw on the side off the base helps holds them togethere, funny thing is i noticed on my 98 k5 it only had one on caliper side, yet the later kx's kyb on the 125,250 have them on both side, yet wp on ktm 450 08 has none, as owe showa's on kx 250f 09 doen't have them ether, usually thy say to heat the base where the loctite is then unscrew them.
i can't quite remember what he said was best for the coating, but i prefer to get valving right for your type of riding, because it cheaper then. Interesting! we had a kx 450f 07 DLC coating starting to dissappear from it leaking fork seal and riding on a sand track.
