Top reviews from the United States
- R & W WallacePerfect and easy to useWorks perfectly, easy to use and self levels. All the good reviews are accurate.
- RebeccaGood productWorked as advertised, applies easily, self levels overnight.
- Amazon Customer.Work says advertised, a good product.
- cameron milbySeem to seal wellLeveled well.
- Debra UlrickNon-Leveling Sealant works wellThis is a quality product that applies smoothly and does not set up immediately, allowing time to tool the bead as needed. Product sticks to my RV materials (metal siding, plastic skylights, rubberized roof).
- MarkGood quality and easy to use.Product arrived on time and in good condition. Exactly what I ordered!
- KWorks greatWorks wonderfully. Helped seal in a crack right before the rain.
- mmwGreat product but damaged in shippingDicor is a fabulous product, 5 stars! I've been using it for a while on my camper. Unfortunately, amazon put it in a too small of a box, and the applicator tip got shoved into the tube. Good thing that none of the lap sealant got on any of the other items that were in the package.
