I have read a number of threads claiming that a final primer coat should not be sanded with grit finer than 400 or 600, or your coat of paint won't adhere well. Given that lacquer adheres by melting into the proceeding coat, wouldn't it be OK to lightly sand the final coat of primer on the BT or nosecone with 800, 1000, or even 1500 grit prior to applying a coat of lacquer spray paint?
