I Changed my seals about 3 months ago. When buying my new seals a mechanic came into the spares shop and told me to get red rubber grease, put it on the seal and smear some in the slot the grease keeps the fliud out of the gaps and stops it crystalising. The pistons slid in really easy too. The grease does not affect the brake fluid so it pressures up fine.
