If there is any area you're concerned with, I really like the Etendabond 4" tape. Amazon about $60 for 50' roll. Grainger $100 for 50' roll.
You can also look on youtube for Rubber Roof Coating. There's a couple good videos of the 2 part mixture and application. When I get ready to coat, I think I am going with the Rubber Roof.
Again, search around on the internet for best pricing.
Kind regards, Doug

Is it recommended to remove the old caulk and recaulk or just run a new bead over the old stuff. My concern is the two main seams on the front and back.

I applied 6 in. Eternabond to my front seam and am going to use 4 in on the back. My rig was relatively new so I did not have to do much prep. I bought a spray cleaner that they sell.

Check out the Youtube Video on RV roof caulking. You can do it either way. If you caulk over old, it needs to be cleaned with solvent and brushed into cracks with a paint brush. If you have the time, I would recommend removing the old caulk, clean and apply new. The caulk is made to peel away pretty cleanly. Make sure you use caulk made specifically for the type rof you have and not silicone. Silicone with damage the roof if you attempt to remove it later and has poor adhesion for top coating. Best regards, Doug

If you plan to just do miner caulk separation (cracks) touch-up, as stated just clean the old caulking surface before applying the touch up. If the old caulking is showing signs of lifting up from the rubber roofing material, then it's best to remove all the old caulking.

As member 'norty1' suggested, the best way to deal with the front/rear top cap seams is with EternaBond sealer tape. When applied correctly it will dramatically reduce the chance of a leak.

Can I put eternabond directly over the excisting dicor? If not, what is the best way to remove the dicor prior to installing the eternabond?

I put mine right over the top of the Dicor. Used the 6" tape to make sure I had enough on each side. No problems so far

If you have some high places where the Dicor is piled up, you can carefully scrape it off using a plastic putty knife. No need to remove all of it, just get it as level and clean as possible and don't slip and damage the roof material, Better to leave it.
