I've used Dicor self leveling lap sealant on the roof of my TT in the past around vent pipes and such. I want to seal the outside corner moldings, around the windows, water heater, stove vent, etc. What caulk or sealant should I use? My camper is an aluminum sided travel trailer. Thanks.

Instead of the run of the mill regular just caulks/sealants which IMO Pro-Flex falls in I prefer the "ADHESIVE"/sealants designed for submerged/marine type applications such as the 3M UV4000. IMO they have superior adhesive properties along with all the desirable sealant type properties.

Larry,
Have you checked the properties of these sealants, the 3M product you use and the Geocel sealants? They are real close in most respects, the 3M product having superior elongation but about the same bond strength on similar materials as the Geocel sealants.

If you have those numbers please do provide them along with where you got them so that your claim they have about the same bond strengths can be verified. I tried to find the Geocel numbers, but couldn't and there seems to be an issue with see the details product specs on the Pro-Flex on the Geocel site now. Also, provide the information saying that the Geocel is recommended for submerged type applications (i.e. waterproof which the UV4000 is).
