Car paint protection has near invisible film that protects against stone chips, scratches and scrapesAnyone who has used urethane or lacquer paint finishes on their car can tell you of the bumpy, orange peel-like appearance these paint finishes often have after being applied. Nothing can be more bothersome to the painter with a passion for the perfect looking finish.
We all hope for that glossy, reflective shine cars have when they exit the sales floor; however, sometimes this is not immediately the case after a fresh coat. For those of us with a passion for awesome paint jobs, this Orange peel is not an “epic fail” as one might instantly think. It is most often caused by incorrect spray gun setup or the ultra-quick evaporation of paint thinner. It can also happen when excessive paint is used or the painter sprays at an incorrect angle.
What Causes Orange Peel?
Hopefully you’ve already watched the video above. If not, I’ll try my best to quote it below…
There are 3 main reasons or a combination of the three that will give you orange peel effect in your fresh paint job or, you may already have it on your stock car paint job.
1. Your Ambient Temperature.
Which means the temperature in the room that your spraying your project in …also the temp of your panel.
2. Your Spray Gun Settings / Spraying PSI
When painting, you must have the proper gun settings, gun flow and spraying psi set. Hint… Wide open fluid flow, wide open and back 1/4 turn fan width and when spraying base coat clear coat paints or enamel you want to spray between 26psi – 30psi.
3. Your Paint, Material Mixture
Which includes your reducer temp, your clear coat activator/hardener temp. When spraying single stage enamels the same apply with reducer and activators. You need to make sure that you are using the correct additives when painting in certain temperatures.
Fast temp for spot panel repairs and touch ups, Slow for painting on 75-90 degrease days etc.
That is really the gist of it.
You can always repair and smoothen out orange peel b color sanding and buffing your panels out. Orange peel comes with the territory. That’s why almost ALL custom paint jobs are color sanded and buffed to a high gloss.
