Resealing Windows on Newell with Caulk, Putty Tape or Butyl Tape?

[Cheri Smith]

Hi All. We are resealing windows and want to know what material we should use to reseal them with.

Caulk, putty tape or butyl tape?? Our local camping world store has both grey butyl and black butyl. Does butyl not dry out as fast as putty?? How easy is it to trim butyl tape that sqeezes out from frame??

Our local rv dealers have recommended both silicone caulk and putty.

Thanks for your recommendations and information! We'd like to use whatever will last "forever".
