Should be ok with soft soled shoes. I try to keep the walking on it to a minimum if possible. Just added a ultra breeze fantastic fan cover to the front fan/vent. Had to remove some of the dicor around the vent trim, replace screws and redo the dicor where the brackets were attached for the cover. Wasn't a bad job at all and went well. We have a 2014 23ss and I've already "touched up" some dicor spots that looked suspect.

If you clean the old and use enough of the new Dicor, no need to remove the old unless it is flacking off, which should not be the case after just 3 years.

This stuff will harnden quickly in the hot summer sun and doesn't level much in its own. In fact I used self-leveling down the sides.

Nasty tough stuff, I would not want to use anything else around skylight...Trilogy had it there from the factory.

Here is a great video worth watching.

I have read that Dicor isn't compatible with Alpha roofs. The OP didn't state what roof he has, but my 2016 23LB came with paperwork from Alpha. If that is the case, then would he need the Alpha caulk like Crockett posted above?

Dicor makes a self-leveling lap sealant for TPO roofs. Look for Dicor 610. I think the EPDM version is Dicor 501. The tubes are different colors - 610 is blue, 501 is yellow-green.

I tried the Alpha product this Spring and it flows about the same as the Dicor I used on the TPO roof of our previous Roo.

Do not use a silicone based sealant.

For the vertical joints where you don't want the sag, I use ProFlex RV Sealant.

I did what the video Igray posted last year and this year had only a small spot to do. Mineral spirits is the key but use it sparingly a clean surface makes it adhere better.
Think about things before you do them make life easier not harder.

X2 on the eternabond tape. You can apply a wide tape if you so desire to have even more coverage. I used a 2" wide width as one can see the top of a pop up and I did not want it looking too strange. It gave me a bit over 1" of roof cover beyond the joint. I am very satisfied with it and will not worry about leaks as I know it seals up tight.

When I had my rv in for inspection in March I picked up a tube of Dicor to have on hand just in case. The service manage told me not to use it around the skylite. So I got a tube of caulk for just skylite use only ,plus a different tube of Dicor for the sides.

Deed is done. Used Dicor. Did as suggested and on video. The cleaning was the hardest part only because it's tedious but also like always the most important part. Under the grim found a few hidden cracks that weren't visible unless cleaned.

Yeah the roof is a little uglier now but well sealed.

All in all a great success thanks to everyone here. Thank you.

Ps. Only stepped in my fresh caulking once. Sigh. Love DIY.
