Anti-Seize Compound

What's the best (readily available) stuff to prevent stainless bolts seizing in aluminium? Ive been using copper based compounds until now but apparently these shoudnt be used here.

Zinc-based anti sieze compond (if you can find a brand name for one can let us know?)
Don't use a compound with graphite in.

I use corrosion-block grease which seems to work quite well and you can get it from ebay.

Hey RW have you tried Alumslip? I've just had a search for an alternative and that's come up.

There's a company trying to say that a graphite/zinc based paste they sell is suitable for marine use. Not sure about that as once the zinc has sacrificed itself it'll corrode like buggery.

I would usually just use water resistant grease but one product I have used with complete success for the lower unit to leg bolts is a compound normally used for sealing oil pipe compression fittings (as in oil fired central heating). You can get it from most good plumbing merchants. The stuff I have comes in a tin with a wee brush inside the lid.

Duralac...yellow stuff that dries.
Or Lanacote from Forespar.

Have used both and tend to use Lanacote on stuff that needs to be undone from time to time.

Also TefGel from Harken. Reassuringly expensive but great product.
