I have a 2012 KZ Sportsmen 14RB (corregated aluminum exterior). I need to reseal my windows. The owners manual says to reseal windows every 5 years. I see three options:
1) Just run a bead of ProFlex RV around the outside of the window frame
2) Remove the window and replace the closed cell foam with closed cell foam
3) Remove the window and replace the closed cell foam with butyl tape (double think in the valleys)
What are the advantaages of each option, short term and long term? What is the best solution and why?
