Pardon me if this is off-topic, but my wife and I recently recently purchased a 2003 Class B R-Vision Trail-Lite with a Chevy engine. Last week, in talking to a dealership repair person, he suggested that we re-seal the "caulk line on the exterior of the vehicle that is even with the floor line.
I checked some stores, and it appears the best product might be using clear Dap caulking from Menard's and a caulking gun.
As you know, there is also a "Flexshot" product advertised on TV, but some on the Internet have questioned the cost of that product vs. the sealant described above.
Any thoughts or help would be greatly appreciated.
