The Meg's water magnets are fairly good, I picked some up on sale for $4 at a local auto store while picking up some oil. But they didn't hold up very well from my experiences. One of them is getting a pretty nice hole in it, from where it came from I have no clue, and you definitely need two for anyhting larger than a mid-size car. I've found Wal-Mart WW towels to be great for doing door jambs. Just order some Guzzlers last week, they'll be here tomorrow, along with my opti-seal and poli-seal :awesome: .
