Guide coat between clear coats

[egor]

Doing my first paint job in 15 years so bear with me, as paints and equipment has changed a bit. I shot PPG radiance in the past, but in Acrylic Urethane, not base coat/clear coat. This paint job is a red candy, gold base with 6-8 coats of tinted interclear. Then, I shot orange flames in the PPG Prizmatique line. Very striking. I knew I would have a bump in the paint due to the coats of prizmatique, so I also laid on the clear. 3M has come out with a guide coat in a spray can, which made blocking out the primer a cinch. So, finally my question: Is it advisable or acceptable to use the guidecoat over the clear to help determine how much clear I have cut away in trying to level the flames? I expect to put one more coat of clear on to do my final polish on, but thought a quide coat may speed things up a bit. Thanks.

DON"T USE A GUIDECOAT ON CLEAR!!!!
just wetsand as normal,sqeegee, and check for shiney spots in the sanded dull finish.You'll have a cluster f##k if you don't sand all the guide coat off.

Listen to Osh,it can be done but it's not wise at all.Just block down the high level and sand the rest.Don't get carried away and break through though.Use 2 coats on the reclear,one coat isn't enough millage for protection becuase the previous don't count now.

Egor...I will elaborate on what the other two posts said:

Sand your clearcoat with wet/dry paper (probably 800 or 1000 grit, depending on how thick you think your clear is....dont sand through!). Sand it with water, add a couple of drops of dishwashing soap to the bucket when your mixing your water, it'll help keep the paper from sticking.

After you've sanded it, dry it and look for shiny dots. These are the low spots. Sand the low spots out (flat). Then either spray your final clear or buff.
