sticky 300ex front caliper. help!!

[SatisTraction]

i went to ride in some slick mud today and noticed my right front tire sliding. i thought a wheel bearing had froze but it turned out to be the caliper was not letting off after i hit the brakes. i took it all apart, greased the sliders (they were froze), removed and polished up the piston, and wire brushed the pins.

it still sticks!!! what else can i do?

Get a caliper rebuild kit. Probably need to replace the piston. But, knowing honda.. it's probably cheaper to buy a used caliper.. lol.
