If you set the compressor to 30 psi you would barely be spraying paint, if you were even able to atomize the paint it would look orange peeled and rough as hell. There are at least 3 regulators in a paint system, and all 3 are required regardless of what gun you have. THere is one at the compressor, one AT the gun and there is the one inside the gun. All three are adjustable and the first 2 should always be filtered.
The one inside the gun is a PAINT filter,not AIR.I know SOME guns come with an air filter inside the gun,but anyone i know removes them because it will mess with the air flow too much and collect water/dirt inside the gun itself,thats why the filter is put AT the gun externaly for the air.
30 PSI in the line is more than efficeint enough to run an HVLP and several other people i know who paint daily,as a matter of fact when i started painting myself again 8 years ago,i had to get advice from pro's i know because i was used to the 70's/80's single stage paint and old guns and all who i asked only run 30 PSI in the line at most because of possible damage to a good gun.
Painting with plastic as a temporary booth is always a no no in my book,the plastic will wave in the moving air needed for ventilation and removal of overspray,..and overspray landing on plastic will also fall off the plastic while spraying and landing on the paint job,ask me how i know.....
As far as the concern for temperature while spraying,they have different reducers for different temps.Slow,Medium and Fast.
As far as a good budget paint line,i like Omni,good quality,nice spraying for a good price,I recently painted a ford ranger for a freind's son's first vehicle with Omni VW Regatta Metallic blue BC/CC and came out beautiful,only paid 90.00 for the gallon and mix ratio is 50/50,so you get 2 gallons out of it.
But everyone has their own opinions/preferences in paint lines,,being budget or top of the line.
