What You'll Need:
- A car or truck that needs some smoothin'
- Spray Bottle
- Wet Sandpaper in varying grits
Choosing what grit sandpaper to use is important. If you start with a grit that is too coarse, you'll be creating more work for yourself and might be left with a thinner paint or primer coat than you wanted. Start with too fine a grit and you'll be sanding until your arm feels like it's going to fall off. A little experimentation will help. As a starting point, if you are sanding a coat of rough primer, you can start with a 400-grit sand paper to knock down all of those little bumps. After some time with the 400 grit, you can move to a 600-grit paper to give yourself a nice, smooth surface to work with when you are painting the car. If you are wet sanding a finished paint job, you definitely do not want to start with a 400 grit sand paper. Too harsh! You'll be ruining your paint finish just so you can do lots of work to restore it again. For a finished paint job that just needs a little more smoothness and shine, start with an 800, or even a 1000 grit sand paper.
Remember, when sanding anything, it's always important to take it slow. Let the sandpaper do the work, and don't apply too much hand pressure as this can cause grooves or uneven sanding. And we both know what that amounts to -- more work!
