I looked at the prices of automotive touch up spray guns at the local automotive paint store. They wanted $215 for the cheapest touch up gun. I went to Lowes and purchased a touch up gun for under $30. Also, when spraying latex, I can spray it in my basement without having to use a ventilation system that should be used with automotive paints. I just use a fan to draw air out the window. I do not have to use protective clothing to protect my skin from the harmful solvents used with automotive paints. The cost of automotive paint is very expensive when compared to latex. Add all of this up, and it can get quite expensive to spray automotive paint. Don't get me wrong, I am not saying latex is better. There are certain applications where latex would not work; like when a high gloss finish is desired. All I am saying is that in the right application a quality finish can be produced using latex at a fraction of the cost of using automotive paint and without being the hazard to your health like automotive paint.
