- A little more. -COP Ig boots are done like this. Once you slick up the ENTIRE inside of the boot, slide it over the spring. Now use a small screw driver or hemostats to pull the spring end from the end of the boot about a half inch or so. Swipe the end of the spring with Lacquer thinner. That cleans and evaporates fairly quick.
That's how you do it if you don't want to take a chance of having to go at it again in the near future.
Once clean and dry, let the spring go, it will recoil back into the boot. The coil is ready for mounting.
BTW- Make sure you use Dielectric grease that will not solidify over time. A lot of them do, - so read the back.
