clear coat
 

what type of clear coat works best and how do you apply it?just pick up some plug kits.

if your just looking to do a few plugs i would say devcon 2ton 30 min epoxy.
its cheep and you can get it at most wallmarts.

just be sure not to get the 5min its not water proof.

if you do a search on how to use it you will be fine.

hope this helps.

thank you
