You have gotten your model car home and got it all ready to assemble. Your next step is to get it painted. You load up your airbrush gun and get it set to go. Next thing you know you have a wad of paint of various colors. Belatedly you remember that you were going to clean your gun later but you must have forgotten. Now your cool new model is a big mess. What should you do now?

Do you love woodworking? Have you built wooden model cars and they look beautiful for a bit and then they begin to discolor? If so then you should consider adding a finish to your model car by applying varnish. While there are two main types of varnish here we will discuss one only. Traditional varnish can be slow drying, and extremely hard to clean up. Water based polyurethane varnish however is much easier to handle as it cleans up with water. It also drys very quickly. Varnish must be brushed in, allowed to dry, and sanded down. It must be repeated so that you get a uniform coating to the part that on which the varnish is being applied.
