I sealed the couple gaps I found with Great Stuff Black which is designed for ponds and other outdoor environments that will come in contact with standing water and create a watertight seal (I've used it in my basement to seal a gap around a copper pipe and it's held up great). After letting it set for a few days as a precaution, I poured water over it and initially thought all was good. Then I tried every other location where the spray foam was and realized it's not even close to a sealed gap. In some places, they put the spray foam on the outside of the metal fender well meaning it actually captures water running down the side and forces it inside.

So it appears I have a few choices.
  1. Reseal the fender with silicon and walk away covering my ears repeating "nanananana"
  2. Replace the silicon with Proflex and cross my fingers
  3. Reinstall the plastic fender flare with a bead of butyl tape
  4. Find a product to cap seal the spray foam/gap (undercoating, rubber spray, etc)
  5. Cut out all the spray foam and install Great Stuff Black


Although I'm really tempted to try option 5, I suspect that's not going to be realistic to actually seal things. My best bet I think is to use butyl tape, but there isn't a lot of edge to work with so I'm not sure it will work.

I guess I'll do that first and if it appears it won't hold a seal, I'll fall back to Proflex. I find this an asinine design to be the standard!

Cut the spray foam level with the siding and wrap the entire corner in eternabond using a wrap applicator tool to form it to the curves?

That sounds like a good option. Does eternabond survive against road salt?

The plastic fender trim is just decoration, and on my trailer, has nothing to do with sealing the unit. It shouldnt require any butyl tape.
My wheel well sheet metal was never sealed against the siding at the factory and resulted in water gathering and rotting the osb floor. Major work to fix.

Sounds like this situation. What did you use to seal the metal wheel well to the wall? I'm heavily leaning towards cutting the spray foam flush and installing a strip of 2" eternabond. I can access most of the length currently but would have to pull the metal skirt to access the last few inches front and back.

I decided the best option was to start by removing the spray foam. I needed to figure out if it was open or closed cell anyway (it's closed cell). So now I have a blank canvas except for the residue. Can I install eternabond tape over the spray foam residue or will that compromise the seal?

Second, I'm assuming I'm going to have to pull the skirt back to get that area sealed. I don't like the idea of ignoring it but it looks like a royal pain to get it off. I can remove the screws, but I'm guessing the metal is sealed on with silicon. To reinstall, I'd assume I'll have to clean the silicon first. Just seems like opening a can of worms!

If there's an easier way and I'm over complicating this, I'd appreciate experienced comments!

I would scrape off the spray foam. Re attach the sheet metal, mask off inside the skirt line and spray everything with rubberized undercoating, then reinstall the skirts back caulking the screws, followed by caulking them with geocell proflexRV.

Can the sheet metal fwnder tray be removed? There are a few screws holdi g the vertical tabs on but im sure its bolted on too. If it comes off without huge disassembly inside that would work.

If the tab had more screws attaching it i would consider butyl tape all the way around as well as proflex caulking.

When I talked to dealer they recommended caulking. I assumed that meant cap seal over spray foam so wasn't interested. I looked up the product (DAP 230) and see that it would work well in the crack as it can fill up to 1" wide and remain flexible up to 600% (presumably meaning 1" could expand to 6"). I like proflex, but it cracks with minimal expansion so this might work here.

Only thing i dont like is that cleanup of cured caulk is cut/scrape.

I reread your comment and think I understand your intent. The sheet metal was held onto the side of the trailer with ~3 screws for the entire ~6' span. I believe you are suggesting to add more screws to properly attach the sheet metal to the side and then use undercoating spray to cover the joint. Once cured, reinstall the plastic fender flare and caulk with proflex.

This is basically what I was originally suggesting except using eternabond instead of undercoating. Except, I don't know if eternabond is able to withstand road salts but undercoating certainly should be.
