Default 95 Coupe Upper Control Arm Nuts

When I installed my Prothane Bushing Kit about two years ago, some of the upper control arm nuts lost their retaining sealant. I used JR epoxy in place of the sealant and it held, but wonder if I can get replacement nuts with the original sealant.

What does everyone else do to solve this problem?

Also, my upper rear Prothane control arm bushings seem to have about 1/8" of wear on them...play in suspension??

Anyone else had problems with these bushings prematurely wearing...have about 40K miles on them...daily driver.

I called Prothane today, and their tech support was great. All I had to do was email them a scan of my receipt and they are sending me a new replacement set of upper control arm rear bushings for each side

As for the nuts, I'm going to install them with Red Locktitie gel when I install the replacement bushings as that seems like what everyone else does

I was thinking about using those control arm bushings but now I'm having 2nd thoughts. Not something I want to replace every 40k miles. Thanks for the info.

I've had a problem with the upper a-arm nuts coming loose aswell. Red locktite fixed it.
