Top Ten Best Car Sealants of 2021

ByNathan Walsh

Sealing your car’s surface is an important part of the detailing process after you’ve polished any swirls, scratches and scuff marks out of the surface. The sealant will fill in these scratches with a protective coating that will serve as an additional barrier to both protect your car’s surface and keep it looking glossy.

When followed up with a wax, you’ll have the best of both worlds in terms of keeping your car looking great with a wonderful glossy shine and protected from the elements as well. Some sealants are more suited for sealing leaks or for keeping rubber and plastic trim in good condition so they can continue to function.

All of these are important for the casual car owner when it comes to the overall maintenance of your car. We cover some of the best and most effective sealants here, both for protecting your car’s paint and for keeping your weather seals leak proof and protected. Here are the best car sealants of 2019.

Best Car Sealants

The Ceramic Spray Coating from Mothers offers super-hydrophobic protection and long-term protection from the weather. This can be used over the top of your existing sealant or even on top of another ceramic coating. We recommend washing your truck, car, or SUV before applying. The car should be cleaned and void of any dirt, road tar, tree sap, or other contaminants that you don’t want to seal in.

This could also be used for marine applications, such as a fiberglass boat or jetski. The product should last roughly 5-6 months before it needs to be applied again. This product features a blend of titanium dioxide and silicon dioxide to provide a powerful protectant against water, dirt, grime, and other potential eyesores on your car’s paint.

1. White RoofSeal Sealant Tape by EternaBond

Perfect for sealing leaky roofs, the RoofSeal Sealant Tape by EternaBond is the best choice. If your recreational vehicle (RV), mobile home, trailer, barn, shed, or any other structure with a roof is experiencing leaks, then this is the best solution to your problems.

In preparation for applying this sealant tape, it’s recommended to thoroughly clean and prime the area with acetone. After the acetone dries (30 minutes or so), then you can install this sealant tape. Cut it to your desired length with a utility knife, peel the backing off and the adhesive will adhere to wherever you choose to prevent leaks from happening.

Strips of 8 inches or less will make this tape more manageable to apply. We recommend using your fingers or a quality application squeegee to firmly and even apply pressure to clear out any remaining air pockets.

This sealant tape is incredibly stretchy, allowing the roof seal to contract or expand with the weather conditions which will minimize the risk of a ruptured seal. It’s also incredibly sticky. If your scissors or utility knife get gunked up from cutting the sealant tape, use acetone to clean them off.
