Ive given some resin infused parts to a paintshop for clearcoating

Overall the surface is pretty good, some areas of porosity,pinholes but its minor.

My guy prepped with 1500 grit, scotchbrite and degreased.

He put on several coats and had issues with pitting, unevenfinish.

Wondered if anyone had any input or ideas on process andpreparation.

Whenever i have done any small parts myself i went for600/800 grit prep, couple coats of lacquer, then 1000/1200 grit and finallacquer coats.

Im wondering whether the 1500 is not enough grit, and the lacquer is seperating/repelling
