I recently ordered paint and clearcoat with flex to paint bumper corners on a silver metallic car and a black one.  The silver job went very well and I am very happy with it.  From about 2 ft away, you can't see a difference.

I am having some trouble with the clearcoat on the black.  The color seems to have gone OK, but the clearcoat doesn't come out smooth.  It is shiny and glossy, but if you looked at a straight line in the reflection, to would appear slightly wavy instead of sharp and straight.  It appears that the coat has undulations in it.  From about 10 ft away you can't tell, but if you get where you can see a reflection, it is apparent.

I followed the "shorter" directions for spray cans closely.

Any ideas are appreciated.

I would try a power buffer on the clearcoat. If you have never used one before, take it to a detail shop or have someone who has used one before polish it. It is very easy to burn the paint right off.

If you want it absolutely smooth, you can wetsand the surface with #1500 until it is absolutely smooth. Recoat the surface again and wait until it has thoroughly dried. Then polish the clearcoat. I would recommend the use of a power buffer to really make it glossy. You can do this by hand, but it will take alot of elbow grease.

Thanks I will give that a try.  If I spray a new layer of clear after sanding, should it be sprayed solid wet and just stop before it runs or should it be a couple of thinner coats?

With a little practice, you can spray wet coats of clear without running. You just don't want to spray it on too dry as then it gets pretty uneven. Even so, you can still wetsand it smooth and buff it out.

You will also want to make sure that the surface of the peice your painting isn't wavy to begin with....From the sounds of it is not....based off of what you are saying about the clear looking ok until you see a reflection in it...if the reflection appears wavy then this is a telltale sign that the surface isn't as flat as possible.....hope this helps.
