No Bull RV Sales Inc.

I’ll admit it… this one made me jump 😅🐝

Now before anyone gets any bright ideas… don’t go poking a wasps nest. Ever. In our case, we already knew this one was vacant before we went anywhere near it.

Just another little surprise you sometimes find when you spend enough time around RV. Keeps you on your toes!

💾 SAVE THIS before your next RV roof job!

Truth is, 3 sealants cover almost everything on your rig. Let’s break it down nice and simple.

💡 Roof seams

For the seams that run across the middle of your roof (around vents, skylights, antennas, or anything mounted on top), you want Dicor Self-Leveling Lap Sealant.

Now here’s why.

Self-leveling sealant does exactly what the name says… you lay it down and it flows out on its own.
It settles into the seam and fills all those tiny gaps where water loves to sneak in.

🪜 Roof perimeter

Now when you move out toward the edges of your roof, things change a bit.

Those seams along the side rails or where the roof meets the wall are where you want Dicor Non-Sag Lap Sealant.

The big difference here is that non-sag sealant stays exactly where you put it.

If you used self-leveling sealant on the roof edge, gravity would pull it down the side of your trailer. Trust me, that’s a mess nobody wants to clean up.

🪟 Side trim, windows, lights, and exterior fixtures

Now let’s move down the walls of the trailer—things like window frames, marker lights, corner trim, and exterior attachments.

For these areas you’ve got two solid options:

• Dicor Cap Sealant (Non-Sag)
• ProFlex RV Sealant

Both of these are made for vertical surfaces, and they stay flexible after they cure.

And that flexibility matters more than people think.

Your RV is constantly moving and vibrating while it’s cruising down the highway. If your sealant dries hard like concrete, it’ll crack the first time the trailer twists a little.

These products stay slightly rubbery, which means they move with the trailer instead of breaking apart.

⭐ The Main Points

So if you remember nothing else, remember this:

You don’t need a toolbox full of different sealants.

Just keep these three straight:

• Self-leveling Dicor for flat roof seams
• Non-sag Dicor for roof edges
• Cap Sealant OR ProFlex for windows, trim, and lights

That’s it. Nice and simple.

A little sealant maintenance now… can save you thousands in water damage later.
