The first thing you need to do is read the "P" sheet for the paint you intend to spray to see if you can shoot clear over it. Some single stage paints don't do well with a clear while others sometimes do and yet some others require the clear to be mixed in with the last coat of color and not sprayed separately.

I would caution that if this is your first paint job that trying a single stage metallic is not a good idea. Metallics can be difficult to spray (especially if you're using low end products) and are even harder when using single stage. It is very easy to get significant mottling with metallics without proper cross spraying techniques as well. However, if you just have to have a metallic I would recommend using a good base coat/clear coat system instead of the single stage. And always read, understand and follow the "P" sheet instructions. That is one basic requirement for success.

Sorry, the way you worded your question made me think you had not painted before.

At any rate, when it comes to paint you should always follow the "P" sheet instructions for the product you're using. If it allows clear coating then do it when it says to do it with the clear coat product it recommends. Remember you're dealing with chemicals and chemical reactions not just something that "dries" through evaporation.

Sometimes painters think they're smarter than the chemists that designed the paint system. Unfortunately when that happens most of the time no one likes the outcome.

When it comes to technique for spraying metallics use a cross pattern on the final coat (90 degrees to the pattern you've used previously). This will help limit mottling which single stage metallics are notorious for.

Good luck.

I know when I painted metallics , on the final coat, I shot a wet coat then backed the gun up and sprayed to let the metallic fall in a more even pattern. There is another thread on here that went into a little more detail from different ones as to their technique. I'll see if I can find it and post it here. Everyone has a different way of doing things but when it came to metallic just about all shot it the basic same way to prevent mottling, striping, or whatever you want to call it. It's not hard, just don't let it get the best of you before you attempt it. You try too hard to prevent something and that is when something will happen. Here is the other thread I was talking about http://hotrodders.com/showthread.php...light=metallic Also go HERE and read down thru the thread. Martinsr. is a paint guru. Do a search for the Basic of Basics that he speaks of. If you can't find it let me know and I'll see if I can help you out further.

In school we did it by spraying the panel wet spraying the next panel wet then backing up to the previous panel we just sprayed and shot a dryer mist coat over it to even out the metallic, but with the paint still wet on that panel it wouldn't look dry. You said you wanted to clear it so I would just buy a basecoat clearcoat system cause the basecoat will be easier to get even then the single stage and your not saving any money going the single stage and clear route

Though I always suggest to go with a base coat clearcoat any time you are painting with metallics, I have cleared over some single stages and the best way I know how is to lay a thin coat of adhesion promoter (I use HOK‘s) after your paint has dried and then apply the clear. The other two ways I know how is to spray the clear right after you paint has flashed, but the clear may have a “washing” effect on your paint. You could also wait until your paint has completely dried and then clear, but your clear may chip off later on. So using adhesion promoter as a mid coat is your best bet.
