Sportyguy...Thats a whole can of worms there. There are many, each have their advantages and disadvantages.
TSPS, I know I may take alot of flack for this but if you want to speed through the process on your first (probably of many) plugs you could skip the sealer and start with a spray primer. Keep in mind that skipping the sealer may reduce the life of a plug. I dont know what wood that kit is turned from. Start with a simple paint scheme and build the kit. Keep it simple. You'll learn alot in a short time, especially if you hang around here.
Skipping the sealler will have his paint peeling off after the 2nd or 3rd time he uses the plug. Most newebies make the mistake of rushing and not letting every layer dry.
Bud, paint it and swim it test it, then move on to how to make it catch fish, all the other stuff will come in time
perty plugs that dont swim = /kill
learn the basics then ho plug bodys
