For those of you that just want a fast fix.... I was doing some electrical work on my car and realized that shrink wrap could work as an insulator..... I bought a variety pack awhile ago and had the perfect sizes to *double wrap up top, and leave it single where the pin goes through the 510 I didn't post this earlier because I wanted to check it out for myself and it's been almost a month now, and it works flawlessly!!! You don't have to shrink it precisely because you can use the top flat part of the pin to guide your razor blade shearing the excess off..... I don't have a picture of that because I didn't want to pull it back out, its a perfect fit..... and I could crank down on my rda w/o issue...... Give it a try, if you either don't want to wait for Paul or want to spend $5 for a grommet that might not even work.....?
This 510 pin... treated with shrink wrap is bullet proof.... TESTED!!
