I normally do two coats on most of my parts.I have a bunch of engine parts I am p-coating for an Audi(coolant pipes,brackets,etc.).The pipes I did came out absolutely perfect.No orange peel,good coverage,no blemishes in color.
Is one good coat acceptable–I’m sure I’ve only done one coat in the past with no issues,this is more a conscious thing being as I’m getting paid to do the job.:)
