I think we all have our own painting recipes and there's no single right way, but I have done up to 10-12 clear coats as I spray them quite thinly, almost a "misting". For me that's helped reduce the curing time a little as each coat dries much quicker. I do a coat each morning and evening for 5+ days, then leave for a couple of weeks to cure.
When I first started I read every thread I could find here on painting technique - there are some great techniques and tips to be found in the collective brains trust here from folks way more experienced than me!
