tips for spraying primer

hey guys,

the main reason im going to be spraying the high build again is to cover up the solvent pop....the car is straight as ive already primed and blocked it twice now...just need to apply primer again to fill in all the solvent pop (most of which is much less than 1/8th of an inch deep....all the deep stuff will be skimmed with putty)....will spraying the hig build on in a couple of coats do the trick for me? after i sprayed it i planned on blocking with 255 on longboards and guidecoat, then moving somewhere between 400-600 wet... the temperature in markham is about a high of 13 degrees celcius ( i know most of you are in fahrenheit...i dont know the formula to convert it)....should that temperature be okay to spray at? and how much time should i let for drying between coats?
