Sealants

I know this is a subject that has been kicked around for decades but I am always looking for experienced voices to help out with things.

When sealing/caulking the RV I have found that Dicor (self-leveling) works very well on roofs but it does not seem to apply cleanly and/or neatly on any side parts of the RV. How do most folks work the transition - where a seam runs from the roof and then down the side of the unit? It would seem that if you started with dicor on the roof and then just kept sealing the same seam down the side, it would get runny and less appealing to the eye, probably due to the self-leveling qualities.

I bought my unit used and the previous owner had done a decent job sealing all the seams, though it doesn't appear to have been Dicor or any self-leveling compound. The roof seams are well-done, though drying out now, and the same sealant/caulk follows the seam down the side onto the body of the coach. It's a tan colored sealant and matches the body quite well but I am not sure what type it is and I can't get hold of the person to find out what they used.

What do most here use and is there a decent caulk that can be used on roofs and bodies of the coach?

Thanks gang.
