Of course you can! That is how a lot of my first builds are, I just got tired of the same powdered coated colors and switched to doing my own. Plus going through an electronic supply house gives me more options for enclosure sizes.
No prep on powder coat is necessary, I just use a lysol wipe to remove any oil or dirt.
Just finished filming a ton of video on how I build pedals using the Sandspur fuzz.
I airbrushed it flat red and showed how I do lettering with paint brushes and paint.
When the video is released I am going to do a contest, whoever comes up with the best idea for the image I will paint it and film it and then give it to them.
What do you think about that idea?
@PedalPCB hopefully I hit all the bases for beginners
