DicorCorp 610SASLW1 Sealant

As anyone that has been RVing for over a decade will tell you, Dicor is the go to product for sealing an RV roof. Yes it does pit (crack but not all the way through) after couple of years, it is easily fixed by another application which one should do annually. It does remain flexible even after several years.

Used this to reseal parts of our pop-up roof, around vent and sides. It is has more liquidity then standard caulk which is good for auto-leveling and sealing. You can still use on a side seal, but just go slow, and may need to reapply as it starts to set up if larger gaps. It does take longer to cure as well, we had a windy afternoon after applying it, and I spent some time the next day picking out leaves and debris that were now stuck to it.

So far, so good for step 2 of sealing an rv fan.

Perfect for hot and cold temps. Have had for years on my roof is ready to be resealed little cracking after five or so. I would suggest any Rver us this product.

Used it to seal around my antenna when I replaced it. Worked as it should, would use again.
