redneck. i have stopped the use of fingernail polish...but why is it worse?
Because heat won't loosen it.. At least, even with red locktite, heat will allow removal.. Fingernail polish anchors 'em and 9 times outta 10 the only way to remove 'em is to drill/mill off the head(s), remove the base - then mill/fill off the stub and drill out the remaining stub and then chase/repair the threads in the receiver..
A few years ago, after a couple base heads broken off upon removal attempts at a local store (and they couldn't figure out why) I asked what they'd used to anchor the screws. When he replied "fingernail polish" I told him to quit using that crap unless he wants to pay me $40/hole to remove the stubs/chase the threads..
Guess what? They quit usin' that crap... Now they have a new(er) clerk who, I found out a few days ago, was usin' that same stuff and (of course) a screw head broke off on a brand-spankin' new rifle and he couldn't remove the remaining stub.. When I couldn't make it budge either I called him up and asked what he used. "fingernail polish", sez he.. I told him then and there to quit using that damned stuff on firearms and leave it for his wife...
Then I had to mill off the top of the stud to within .002 of the receiver, center-drill the stub, finish drill with a #31 (6-48 screws) and then chase the threads with a tap..
Cost him $40... If he'd have used even Red locktite, the cost would have been about $5-10, tops...
They use it again, they're gonna pay - again...
