Getting the 2004 Bubble Wagon ready for another Michigan winter. I noticed a little rust starting on the bottom seams of the tailgate and doors. These are the seams that rust always finds first on most vehicles and I'm sure most of you know the spots I'm talking about. I hardly had any rust at all but I'm thinking about prevention. I want to seal all the doorskin seams so I don't have to worry about it. Looks like 3m seam sealer is the way to go but wanted to know if anyone on here has done this?
