With the Door Rack Painter you can paint and dry both sides at the same time!
How it works:
The edges of the door are placed on the bent rods, resulting in minimum contact and therefore allows one to paint both sides at the same time.
Two methods for leaving no marks:
Basically: Always paint the backside first, don't spray the sides yet, grab from the sides ant turn the door around. The least important part of the door is the back edge. Now the painted side will lay, because of gravity, on the bent rods, these will result in minimum contact on the back edge only. Spray the front and the sides. When spraying the sides make sure to aim sideways from above to avoid overspray on the back of the door.
Utilize the grip holders (big or small). The reason why they are called grip holders is because they allow you to hold the back edge of the door on a 45° angle without slipping. Now the doors are ready to be laid on the dry rack and don't forget to position the rods for the next door.
If you put one coat of primer and two coats of finish and let them dry in between, it is acceptable that you find small marks on the edges. This touch up is very minimal, take a chip brush or foam brush and tap the edge with tip of your brush (most of the time it doesn't require any sanding), remember that any possible marks are only on the back side edge. (the least important part) and also remember that it's being sprayed 2 to 3 coats, causing the marking that needs touch up to be very minimal.
Many reviews from painters that are surprised on how little marking there is.
Second method: Follow the steps for spraying the primer and the first coat on both sides. But in your final coat, spray the back side first again, making sure you have no marks from the first two coats. However, if there are any, sand the edge gently with a small piece of 320 sand paper. This should only take seconds. Spray the back side and load it up and place it in dry rack without painting the front. This time let the back side dry to the point where it is not liquid anymore (doesn't need to be super dry). Finally, spray the front side and load it up, and let that dry. This way takes a little longer, but you are saving a ton of time on the primer and first and coat. But, it totally eliminates all marks.
About 70% of the time it is perfectly ok to spray all coats at the same time with a tap of touch up on the back edge and have an excellent finished product. About 30% of the time, especially if you have a high gloss finish or the back edge of the cabinet door doesn’t have a sharp edge and is rounded. It is advised to spray the final coat separately, just like the second method, this way the result will be no marks.
