Dicor Self-Leveling Lap Sealant vs Forever Extra Leveling Lap Sealant

Dicor Self-Leveling Lap Sealant is the safe default for routine RV roof maintenance: sealing vent flanges, screw heads and edge trim on horizontal surfaces. Forever Extra Leveling Lap Sealant is the better pick when you are filling deep voids, heavy build-ups or thick gaps, and its 20-year warranty is the strongest durability claim of the two. Dicor has the longer track record and a 4.5-star rating from 64 owners; Forever is the heavier-bodied, deeper-fill formula. Both are rubberized, self-leveling and UV-stabilized, so the choice comes down to job depth and how much material you need.

• Choose the Dicor if you are resealing standard roof penetrations, screw heads and trim on a horizontal RV roof and want the proven, widely used formula.
• Choose the Forever Extra if you are filling deep voids, thick build-ups or large fixtures like caps and skylights and want a 20-year warranty behind it.
