I have a small leak where the antenna coax enters the roof on my 2009 22T. The sealant is a non-hardening white putty type. Does anyone know what specific sealant this is? Do I need to use the same sealant to reinforce this seal or can I mix? If I should not mix, any other recommended waterproof, non-hardening sealants for this application?

Thanks,
Chris

If you are the original owner the warranty should cover that fix if it has been less than a year since you bought it. I don't know what the stuff is made of.

I've been buying "Lap Sealant" made by DICOR CORP. It is available through most RV dealerships. I use it to reinforce the sealant as it ages and shrinks. It is self leveling and seals real well. I usually check the roof when I clean it.

I use a 50 year POLYURETHANE caulking , SIKAFLEX 1a , it is used in the sheetmetal industry.The PROFLEXRV caulking made by GEOCEL which is a tripolymer, did not work for me. It harderned and cracked in a year!! 1997 towlite LES
