BEHR has been around for years and has manufactured everything from paints to sealers and coatings. Their products are available just about everywhere and their price point is very affordable. If you are looking for a temporary seal, or a temporary coating, BEHR is a great option.
Many retailers offer dozens to hundreds of color options. Each product is available in solvent and water based. When it comes to convenience and product availability, and even company ratings, BEHR gets an A++ in our book.
The only downfall to using BEHR is that the solutions are temporary. Most of their coatings last 6 months to 2 years. While their claims are very accurate, and their product of quality grade, they are not designed for industrial or commercial applications.
For industrial and commerical applications, consider a manufacturer offering professional grade products.
