i also drove for a couple of days with the windows down and it finally cleared up.

is there really this many leaking bottles? look at the number of people posting here about it. sounds like we could win a class action law suite

+1 for the leaking bottle. i thought i must have had the cap on crooked or something till i read this.

Lucas bottles leak also

Had a whole bottle the one for 100 gallons leak out in the sleeper door of one of our cow trucks...... Still cant get it all out!

GUMOUT are pretty tight though

What is wrong with all you dopes , you have a big bed behind you to put all the stuff you dont sit with when driving. When picking up a guy for work in the morning and hops in my brand new truck and puts his toolbag (framing carperter) rite on my clean rug between us and I look at him and point to the big square thing behind us with tool boxes on it. Dont carry $hit in your truck cab you have a truck , put it in the bed. F'n dummies.
