FIRST OFF: URETHANE ENAMELS, WHEN MIXED, ARE VERY TOXIC TO HUMANS. You MUST wear a VOC compliant respirator at minimum when using these type of paints. A fresh air system is recommended, as is a painter's suit. These paints omit Volatile Organic Compounds, which are deadly the the human liver. DO NOT try to paint at home without an approved respirator, at the minimum. Ask your paint salesperson which one to buy. 3M makes a good one for under $20. | FIRST OFF: URETHANE ENAMELS, WHEN MIXED, ARE VERY TOXIC TO HUMANS.

| − | Urethane enamel comes in two forms: Single stage, and Base coat/Clear coat. Single stage is the easiest to use, simply mix the two parts together, (The paint and the hardener) then reduce to spray and go at it. The single stage paint like the base/clear, dries chemically by cross-linking together at a molecular level. Old lacquer paints and the Dupli-Color stuff at the local auto parts store dry by evaporation of solvent leaving the paint behind. Urethanes are MUCH stronger, as the name implies, they leave a urethane (plastic) coating on the car. Much better then old technology like lacquer. | + | Urethane enamel comes in two forms: Single stage, and Base coat/Clear coat.

Base/Clear, the other type of urethane, works a little differently. You first spray the color on the car, (The base coat) then apply a few coats of clear urethane over the base coat. The base clear has advantages over single stage, so let's compare the two. | Base/Clear, the other type of urethane, works a little differently.
