Underbelly expanding foam

[RDP]

Does anyone know the exact brand name of expanding foam used to seal around the pipes and wiring in the underbelly of the Micro Minnie trailers? I have a new 2306BHS and found some missing gaps that the factory missed. I do not want to travel to the dealer at the present time.

Those gaps are probably there to allow technicians to repair/replace pipes and wiring more easily.

Great Stuff - they make about 10 different varieties. For an RV I'd consider their GreatStuff PestBlock Insulating Foam Sealant. Can fill up to an 1" gap.

These are gaps in the foam insulation where it did not quite fill in when expanding. I want some foam like the factory uses.

A call to Winnebago Tech Support will get you that information. You would want a UV resistant closed cell foam that will not absorb liquids.

thanks Randy, I've wondered that myself! I recently tried an alternative DAP brand for some repairs around the house - it was WAY too soft, even after cured. will go back to Great Stuff, and the particular product you recommend for my Micro Minnie underbelly foam repairs!

I ended up using the Black RV Great Stuff. I though that I would need just a little, but once I was under the trailer I found lots of gaps and entry points for insects, mice & rodents that were missed by the factory on this new trailer. I used nearly the entire can.
