Are you a fellow sufferer of analysis paralysis? I am. Choosing a self-leveling sealant is enough to set me back three Ibuprofen pills. Options abound. And as an RV repair technician, I must carry sufficient stock to re-seal all roof types, all colors, at any time. I don’t want to stock $700 worth of self-leveling sealants, so how can I consolidate my choices while providing top quality?

Admittedly, like some other articles of mine, this one is needlessly nuanced. If you’re simply after the best self-leveling caulk, then here’s what I’d tell you:

• Choose a self-leveling caulk that is compatible with your roof material type.
• Thoroughly remove or clean any existing caulk to ensure the best adhesion.
• Inspect your RV roof sealants twice a year: spring and fall. Look for bubbling, cracking, peeling, or disintegration. 
• You get what you pay for. (It’s cheaper for a reason.)

If you follow those four rules, then you’re already ahead of the curve. Any RV-approved self-leveling sealant, properly applied, will do the job. Either use a “universal” self-leveling sealant like Dicor 501, Alpha Systems 1021, or XTRM-Ply Universal, or even better, use the recommended sealant by your RV manufacturer.
