Initial filler was ripped back with 120 then onto 240 all dry sanded
Machine sanded with 320 before first primer coat.
More filling to do yet then another 320 - 400 wet sand before the next coat of HB primer - if that looks good then 600/800 sand before first colour coat.
Not 100% sure what paint system I'll be using yet though!
Ah ok, just asking, cos I'll be attacking my CF bonnet with 2000 grit W&D to smooth the surface where birdshit has eaten into the toplayer, hope it's gonna be fine, just bricking it at the mo before actually commiting to the job, but then again, I did take a Dremel to it when fitting the Aerocatch Bonnet Pins.....
