Recommend a sealant or caulk

Hubby is in the process of scraping away old caulk/sealant on class C...around windows, door, compartments. Anyone have a recommended goo to reseal with? AND what do you actually call it. We can use amazon prime or camping world (15 minutes away).

  • I have used Geocel and one recommended by the factory called Manus bond 75-am, I was really impressed with both products. I purchased both from Amazon.
    I always use Dicor on the roof.

    For other things, I find OSI Quad Max works fairly well and is not too expensive and is available at big box stores. The Max version is definitely nicer to work with than the standard OSI Quad, and the nozzle on the tubes can be unscrewed and cleaned out after storage should it goober up which is a big advantage as far as I'm concerned. This is a polyurethane-based compound, I believe, not too much unlike GeoCel Proflex.

    For little things like door hold-open catches, plain plumber's putty also works pretty well and is comparatively neat and clean to work with and easy to remove should the need come up.


    Thank you. No roof stuff at this time just horizontals and verticals. You mention PROFLEX Geocel and that was what i was just looking at...use that?

  • My all time favorite is Dicor for vertical seams. Other have what they like.

    Do a google on the rv sealants and then watch several you tubes from experts like rv dealers/rv repair shops shops/etc.

    And follow the sealant mfg instructions.
