As a general rule, most cars can be painted using a 30 gallon air compressor. In fact the important thing when choosing one is not how big it’s tank size but instead merely CFM rating which measures airflow in cubic feet per minute (CFMs). You want this high enough for your needs so that you don’t end up with low-quality paint jobs!
This is a question that gets asked often, “How many CFM do I need for spray painting my car?”. Not everybody knows about the air compressor and its responsibility in supplying enough airflow to paint your vehicle with consistency at maximum power rating (3CFMs). You can find 3 cfm rated guns on sale around $100; they’re perfect if you only want light duty use or are doing small projects like touchups! Higher end models may require 6500+ bpm but these will typically be able bodied solely by using special nozzles designed specifically towards large jobs which adds cost.
When it comes to spray painting a vehicle, the higher CFM rating is important. Without enough air flow in your spray gun and compressor combo will not have enough power for complete coverage of paint on all parts being painted with minimal bubbles or missed spots from uneven application. A high volume low pressure HVLP type compressors usually provide just what we need when completing auto body jobs at their finest levels – close to 20 cubic feet per minute!
The conclusion of this article is that you absolutely can spray paint your car with a 30-gallon air compressor. The higher CFM and larger gun will allow for quicker work, but it doesn’t mean the whole vehicle has to be done in one session. You may see people say they need a compressor size over 20 cubic feet per minute (CFMs) or large diameter sprayer because those provide more control when painting surfaces such as hoods and roofs where mistakes aren’t wanted – which we all know how much time these tasks take! But even small compressors offer plenty power output enough if used correctly so don’t let high airflow numbers turn away from getting creative on projects around home. The 30-gallon compressor and spray gun with a 3 CFM rating or higher will suffice just fine.
