tips for spraying primer

hey old vart,

i was planning on swiping the deeper areas with putty (thats what a body guy told me) and then the spraying high build and hopefully filling in the rest of the solvent pop (most of the solvent pop is only visible because of the guidecoat i have on, and when i run my hand over it i cant really even feel the pitting- only slightly in some spots)....Is there anything i should take into consideration when spraying over solvent pop? this is the second time it has happened to me, which is why in now going to spray the primer on instead of rolling it on...is there anything else i should know because i dont want to waste my time spraying primer and then having the pits come through again

thanks guys
Matthew
