Quoted from vid1900:After a few days your clearcoat will be hard enough to wetsand out any crud that fell into your clear.
The playfield has to be ABSOLUTELY smooth! Any trash that you can feel with your fingers will telegraph through the Hardtop.
Run your hands over the finish and find any trash. Wetsand it out so that the playfield is totally flat.
If trash fell onto an insert, sand it out AND buff the area to a mirror shine. Remember you can see the inserts through the Hardtop.
I did not have any pictures of this step, as I shot the clear in a downdraft paint booth - nothing fell into the finish (I'm not always that lucky, lol).
Sorry for piling on to a 6-month old thread, but thought this might be helpful.
One trick I picked up from my car detailing days is to put your hand in a baggie (e.g.: Ziploc) when feeling a surface to see if it's smooth. The baggie helps amplify any imperfections in the surface so they can be better felt.
Might be overkill for a PF, so please feel free to tell me to STFU
