- dryflyExplorerI'm pretty good with caulking but my results with ProFlex were terrible. I applied as small a bead as possible and used my finger (dipped in mineral spirits) to smooth out. It sets up so fast you barely have time to make a single pass.
This application was around my windows and the trim on the outside of the trailer. After about one year I've noticed the ProFlex is already starting to crack.
Also it is a large pain to try to get the old ProFlex off when recaulking. There is no doubt it is the best caulk to use. Wonder what would happen if one just used a good grade of exterior latex caulk??? It has a little flexibility to it, and is easy to apply and remove. Doubt it would last as long but much eaiser to work with. - spadoctorExplorer III buy my caulking from the dealer....he sells the caulk used at the factory made(or marketed) by Alpha. One is self-leveling the other is for vertical surfaces. Both are great. Try calling your dealer for the answer

Let me rephrase my question: the exterior compartment door frames on our Carriage trailer have a white sealant frame to wall. It is applied in a narrow 45 degree angled bead. What product is it?
On my 2011 Cameo, on all of the exterior seams, they used silicone.
I've been going round the trailer cutting it all out, since 50% of it didn't bond. Each vertical seam has taken me about 2 hours to dig it out, and clean out the silicone with special cleaner from Home Depot, before I re-caulk with Geocell Proflex.
If I had a chance, I'd go shoot someone.

I note that Geocel has a RV EPDM roof sealer.
I was trying to figure out if geocel was a urethane type of sealer but just found that it was a "polymer" with no further information so I assume it isn't.???

Geocel does make a EPDM non-solvent roof sealant (white) but they do not publish ingredients as it is proprietary blend. Secret - BumpyroadExplorer

I can't say for sure, but I used GeoCel ProFlex white with good factory like (original) results. It is a bit fast setting, so best to apply with a narrow cut tip then tool (if necessary) by using a touch of mineral spirits on your fingertip...

Dicor has self-leveling for roof seams, tank vents, fan vents etc. (NOT around A/C Unit---that uses a gasket)
Dicor has non sag sealant for vertical/sidewalls
NEVER use Silicone on an RV......it doesn't always stick. It leaves a residue that will not allow any other type of caulking to stick....even more silicone and has to be completely removed using a 'silicone remover---solvent' which can cause more damage than good. DON'T USE SILICONE
