Dale,
Once you get a feel of what to look for as your spraying you'll be able to judge how much to use. As your spraying it, it will look a little dull until the stuff starts leveling, so keep that in mind as your spraying.
With this stuff, less is more.
It's raining so about all I did today was start making the gauges for the Mustang. Here's a mock-up of how they look. I still have to finish the rest of the details. I have them printed and just need to drill out the holes.
L8TR,
Eric
