How to paint 37-3U Enclosure Fourth Of July Version

Happy Fourth Of July!

We want to take this opportunity to do something that we have been planning for a while now, paint an enclosure. Especially during one of the biggest holidays in the USA. We will show you step by step how to paint the USA flag on one of our most popular items, rack-mount enclosure 37-3U.

Let's Paint

Make some basic marking to visualize the layout.

I use this ruler to divide the space up equally.

Sand and paint the primer on the enclosure surface.

Divide the box again using the same method.

Make the spacing for the stars.

If you use the ruler to divide the spacing, you can also use it to make the tape the same size.

Cover all the areas that are not supposed to be painted red because we are going to paint the red stripes.

Take your time and go over it a couple of times.

Peel the tape to see the result.

Repeat the previous step if you want to touch up the white stripes.

Apply the stars on the correct marking.

I applied 2 layers just to make sure the paint doesn't leak through.

Cover the area that you don't want to paint over.

Wait until the paint dries completely. This is a very important factor because you don't want to damage the blue area. There will be a video below show how to complete this step correctly.

This is the rack-mount enclosure 37-3U final look.


Fourth of July is one of the biggest Holidays in the US, Americans celebrate our Declaration of Independence. On this day, we usually gather with family and other members, eat, drink, and celebrate with each other. At the end of the day, there are large fireworks to memorialize the ones that passed away and cherish loved ones that are still here. This enclosure can also be used as a fireworks control or launch station, the metal structure will provide a solid foundation for any of your projects.
