Window Sealing and Vertical Seams

[Spl170s]

First time visitor, second time poster here.

I am seeing where around my windows some of the factory sealant is starting to let go. What products can be used around windows?

Next, vertical seams where front connects to sides... what kind of sealant can be used for this? I have a fiberglass type side walls.

One point for sure, don't use a Silicon Sealant, we just had some repairs done and they used an Elastometric Sealant on the seams, Usually the windows have a sealant tape used when they are installed, I would think the elastometric tube sealant could be used on the outer seams unless you remove the windows and clean and reseal them. You should be able to get the items at any good RV parts store.

It would be best to remove the windows, clean off all the old sealer, then reinstall them using butyl putty tape. Once the ooze out has stopped, you can trim off the excess and seal the top and sides with an approriate caulk as MikeAmber suggested.

If there is some molding covering the sidewall seams, carefully remove it and reseal using the putty tape. Again, once the excess putty has been removed, you can use a caulk to seal the exposed putty.
