• Spar urethane finish used to be termed “marine spar urethane” because it was used extensively on boats. The spar urethane application was perfect for boat use because it makes wood waterproof while providing a finish that is both durable and perfectly clear. Contractors and consumers doing home repairs began using the product for other wood in and around the house, such as doors, window trim, counter tops and wooden garden furniture. - Source: Internet
• Although the applied product provides an easy-care finish, getting a spar urethane finish applied nicely is not that easy. Given the thickness of the urethane, it’s rather like trying to apply a thin, even layer of corn syrup. That’s where sanding comes in.

• The purpose is to flatten and remove the bubbles without removing all of the polyurethane coating. The sanding is more aggressive than the steel wool, so proceed with caution. Once the bubbles are removed, you have two options. If the effect of the bubbles was minimal, you may get away with buffing and polishing the surface to get the required finish. However, if the effect is severe you’ll need to apply a further layer of polyurethane to level off the surface. - Source: Internet
