I've been using some Anti Sieze that we use for work "Auto Mechanic/Tech" & so far it seams to work in my Traditions Yukon but I think I may try the Teflon Tape next time...

My Yukon came with the cheap plastic cights as well, & I bought the Tru Glo Sights from Cabelas & may be installing them soon "or may wait till after the season is over..
