What grease to use for Rear caliper slider pins?

[HarryJT97]

So I've read online that you should use Red rubber grease to grease the slider pins on the rear calipers, however I cannot get hold of it until Monday and it needs to be done today Ive heard that I should not use Copper Grease, but some say I can use Moly Grease or a silicone based grease? Anyone can help me out here with which one to go for?
