Funny thing- I went to Lowe's under the facade of home improvements/yard work hoping to find boat stuff. Asked the guy about 3M 4200. Got the usual deer in headlights look and went on wondering. Stopped at Walmart on the way home and just happened to stop on the 12' section of boat stuff. WAALAA! There at Walmart was 3M 4200. and a few other products I'll put down the West catalog and go get the groceries a little more now!
