Just did this a month ago......

Completely clean both surfaces with a gasket scraper and brake cleaner.
Check and make sure diff cover isn't badly warped from over tightening.
Apply 1/8" bead of Rtv ( make sure to use one that won't break down from gear oil)
Let it set up for a few minutes
Install cover and hand tighten bolts (very important)
Let this set for at least an hour or two( when I did mine it was 40-50 degrees outside so I let mine set overnight)
Next hand tighten down the bolts (make sure not to over tighten)
Fill with oil

Get a lube locker gasket and follow their torque sequence. It works perfectly.

Both ways work fine but for the little extra $ the lube locker sure was nice, no mess, no waiting, no worries.
If it's not supposed to move and does use duct tape.
If it's supposed to move and doesn't use WD40

I used RTV last time I changed my front fluid (couple times a year- was have mucky swampy trails with river crossings) I put the bead on then started to do something else for it to cure for a while.

The next day when I remembered I never put my ARB cover back on my front diff I decided against cleaning it all off and starting again. Figured it would act like a lube locker gasket (and hopefully not stick to both sides when I pull it again). Been several months and not a drip. :-) I did have a nice consistant bead though- if it had been a bad one I would have probably started over again.
