I changed the rear pads on my G3 integra today, i was in a hurry and forgot to put the shims on the new pads, also i didnt use any anti-squeal grease, they work fine and theres no squealing, so should i bother taking them off and putting the shims and anti squeal grease on them?

 

im about to do my pads
what kind of grease and where should i get it
my helms just says "grease here" (pad surface, and shim)
