And another tip on flow coating: It is best done after the LAST coat of clear has cured and been wet sanded. Then you come back with the over-reduced clear and apply 2 wet coats to give it a super smooth finish. HOWEVER...this process should be used for show cars only that don't see too much sunlight. When you over-reduce the clear, you are decreasing the film build (mils) of the clear. Clear coat is UV protected ONLY at a certain film build. Any thinner than the recommended film build, the clear will fail over time (i've seen that happen in as little as 6 months in our Texas sun.)
The guys at SPI(Southern Polyurethane Inc.) recommend doing just that. Let the first coats of clear cure, wet sand with 400-600 and then flow coat on 1-2 more coats with the over reduced clear.

Just use a hotter reducer..... example: PPG DT898. Or I've even used a cap full of blender per quart of sprayable clear

just wetsand and buff the darn thing, clear is designed to spray with a certain mixture for durability reasons. If you want a wet finish then follow this process

Id clear it with three coats, let it sit overnight. Sand it with 600 then clear it with three more coats. Then id cut and buff.
I believe with that many coats the solvents are never going to come up. Which will cause problems later.
