A Guide to Spray Gun PSI When Painting Your Car

When painting your car, getting the right spray gun PSI (pounds per square inch) is crucial for achieving a smooth, professional-looking finish. The correct PSI setting depends on the type of paint, spray gun, and air compressor you’re using.

Understanding PSI for Different Paint Types

Base Coat: Most HVLP (high-volume, low-pressure) spray guns require 25-30 PSI at the gun for an even base coat application.

Clear Coat: For clear coats, a slightly higher PSI, around 30-40 PSI, helps achieve a glossy, flawless finish.

Primer: Primers are thicker and may require 20-25 PSI for proper atomization and smooth application.

Adjusting for Best Results

It’s essential to adjust the air pressure at the regulator and test spray on a scrap surface before painting your car. Too low of a PSI can lead to orange peel texture, while too high of a PSI may cause excessive overspray and paint waste.

How To Prepare For DIY Car Painting

Are you ready to give your car a fresh new look? At Paint for Cars, we believe anyone can achieve professional-looking results with the right preparation. Here’s a guide to get you started on your DIY car painting journey.

Choose the Right Environment: Painting your car requires a clean, well-ventilated, and dust-free environment. A garage is ideal. Ensure it’s completely clean and free from dust that could stick to wet paint.
Gather Your Supplies: you’ll need an air compressor, paint spray gun, orbital sander (with multiple-grade pads), hand sandpaper (grits 120-800), solvents, masking tape and paper, body filler for any repairs, safety gear, and the actual paints and coats for your project.
Prepare the Surface: Wash your car thoroughly to remove all dirt. Once dry, sand the current paint down. Start with 180-grit sandpaper for rust or damage, proceed to 320-grit to smooth out scratches, and finish with 400- to 600-grit to prepare the surface for new paint. Pay extra attention to edges when sanding, as improper sanding in these areas can lead to paint peeling from the edges of panels. Repair any dents with body filler, and you’re car will be ready to go.
Mask Off Areas: Use masking tape and paper to cover windows, mirrors, and other areas you don’t want to paint. This step ensures a neat and professional finish.

Patience and preparation are key. Take your time, and you’ll be rewarded with a car that looks as good as new.
