I want to finish painting my engine bay, hood hinges, and bottom of hood Saturday with a harbor Freight Tools hvlp $19 gun and 8 gallon compressor. I have a water filter for it too. If I reduce it 2:1, will it paint ok in short bursts? I used custom mixed aerosol cans for the front areas but they are pricey at $28 each. Doesn’t have to be perfect.
