Thanks guys, clearly a few opinions on this. As I have some copaslip, I'll probably use that. There are lots of different types of red grease, I have seen some advertised as "sticky". I also have some in the garage that IIRC I bought to lube some new fork seals in my mountain bike, it isn't really any thicker than the "standard" grease I have in my grease gun. The thickest grease I have is Lithium grease, used for the wheel bearings in the mountain bike.
