Best Clear Sealant

What is the best clear sealant/caulk to use for the exterior of my travel trailer? I want it to caulk around things like the fresh water fill, cable hookup, etc.

Thank you,

Bruce

    I won't put that stuff on again. Even though I like what pro flex does and how it goes on, it did not match my color. Even though color said "clear" it really was a glazed look. And a pain to remove.

    Call who ever made your trailer and see if they have "calking sheets" to get direct replacement of what OEM put on in first place. Here is one example

    Hit a link on left hand side for example.

    Using the correct stuff your RV won't end up looking like a patch job covering up a patch job.
    Not my experience at all with Geocel Tripolymer sealants.
    Did you apply the Geocel product over an existing caulked joint or did you remove the original sealant? Is it possible the two sealants reacted or mixed?


    "Is it possible the two sealants reacted or mixed?" I don't think so. No it stuck real good. And I like pro flex. I used some where it would be visible and it didn't match color at all. Color of proflex is sort of egg shell white vs the ford "oxford white". Good stuff, sticks great but didn't match my color so took it off and replaced with some stuff that is actually the color of rest of rv.

    Pro flex is good stuff, if you don't see it. I've got a little dip right next to my skylight or "bird bath" maybe 1/8 inch deep. So water sets up there. Dicor lasted 3 years but was beginning to show wear. Poured some pro-flex into the "bird bath" and I'm happy so far (about year and 1/2 ago). But nobody's going to see it on top of roof where the trim work around the rest of rv, the color difference would show up big time. If my color matched the pro flex color I would use it everywhere.

    I tried calling Ford and geo-flex to see if I could tint. Ford said to e-mail the question to somebody, never got reply and geo-flex said they didn't know.

    I called Inland coatings and asked what to do to tint and they said take to any Sherman Williams paint store and tint to their spec of 955 series or 755 (can't remember). I do have a quart of tinted of rc 2000 http://www.inlandcoatings.com/rc2000.htm matched up to Ford Oxford white exactly and like it a lot. For some reason a lot of people think EDPM is only on RV roofs. Read some of inland coating material. Good stuff but does not last as long as pro-flex IMO but a lot easier to get off when have to re-do in years forward. I don't have anything against dicor either, but don't like driving 30 miles one way to get it and is not the cure all as many believe.

    Use what ever you think is best. For me, I put on just a little dab somewhere that is not visible and see how it dries up color wise before re-doing RV. The color white covers a big spectrum.

    Thank you. That stuff isn't cheap -- must be good. It has good reviews on Amazon.
