[Towertalk] 402CD coil mods

[K9AJ]

Hello All,

I wonder if those who have modified the loading coil assembly on the 
CushCraft 402CD (replace the existing screws that attach to the coil  w/ 
stainless steel bolts & locking nuts) can tell me what material they used 
to re-seal the loading coil assembly?  If shrink tubing, what size (the 
aluminum tubing the coil is mounted on is 5/8")?  Would high quality 
electrical tape work?  Any thoughts regarding this mod?

Thanks,

Mike/K9AJ
