Advice for Replacing Front Cap Sealant

[itat]

I noticed that the sealant at the joint where the front cap overlaps the sidewalls on my Rockwood Signature UL is beginning to crack and will need to be touched up or replaced. I need some advice on the best method to do this.

Can I clean it and caulk over the old caulk or do I need to remove and replace it? Either way, what method and materials do you use to prep?

When I caulk, I usually use painter's tape to get clean lines. I'll be using ProFlexRV sealant.

I recently found myself in need of replacing the corner molding on mine. Through my research I found a product called seal tite corner seal. It's used to seal the gap in the the joining panels under the molding. There are several you tube videos on the product. The seal tite is a sealing tape with a fabric outer layer. Think of it being almost like aluminum tape. It combined with butyl or the sealant you mentioned will make for a great weather tight seal and repair. The seal tite is reasonably priced but shipping is inflated. But for a superior repair and piece of mind knowing there won't be any future water penetration, it's worth it.

The way I describe would require you temoving the corner moldings and cleaning all the existing sealant off first.

Search for the product on you tube and decide for yourself.

I plan to use Eternabond tape, something like this guy did:

Thanks. I'll eventually use Eternabond on the caulked seams on the roof but it's not for the vertical seams where the front cap overlaps the side walls. See the picture below.

I'm just wondering if others completely remove the old sealant and re-caulk or if they caulk over the existing sealant. I was planning to use painter tape to mask off the area that I'll be caulking and I'll use Geocel ProFlexRV sealant. I just don't know if I should remove the old caulk first, and if I should, how do others do that.

I have used the Geocel ProFlex RV sealant around some storage compartment door frames and tail lights it worked great. What I did was to carefully cut around the door frame edge, and not cut into the gelcoat. Then used a razor blade scraper to carefully come in underneath the caulking from the outside of the old caulking in towards the frame. Then clean using acetone and toothbrush if needed.
Use a good quality caulking gun. You can wet your finger and gently pat the caulking to get it to fill the void and level it out. Just take your time and don't get in a rush.

Proflex is great stuff. I would recommend removing as much of the old caulk as possible. If the old caulk is silicone based, then you want to remove ALL of it. A hard plastic scraper, a can of prep-all or acetone, some rags, and a good amount of patience will be required to remove it.

Thanks for the advice. I also found this thread...

Looks like I'll need a scraper razor blade and something like isopropyl alcohol to get as much as possible of the existing sealant off before re-caulking.
