I have been running into all kinds of issues with spray painting my pinbot (using automotive acrylic paint) my cabinet.

After having to sand back my black finish down to the primer, learning from my mistakes I really made sure the surface was clean and smooth.

When painting I did not get enough coverage on parts of the cabinet. Therefore the top part of the cabinet is perfect and smooth, but the button half is feeling a bit rougher and when you look at an angle you can see the difference and can see the bottom half didn’t get enough paint.

Can I fix this by spraying a new layer on the cabinet?

I really hope someone can answer this because I desperately like to avoid having to sand the whole thing again if I don’t have too

This is what it looks like.. the paint is quite shiny so with the bright light it looks like there is no coverage, but that’s just the reflection.

A closer look does show some “specks” as well that I did not notice before. I can’t few them and as I said before I really made sure the surface was smooth and clean before painting

Im spraying at 300-400 mm distance and spay from left to right.

I spray all sides and then wait a minute and repeat the process once or twice

I used 400 grid paper (as advised by the paint shop), using acrylic automotive primer and topcoat. I sanded my primer layer to.
I thought I might have been spraying too close.

Can I sand with 800 grid and respray without having to prime again (providing I don’t sand all the way down to the ply)?
Will it also help reducing airflow when spraying?

Thanks for the info..

Not sure what my airflow was. I used a CFM 15 compressor that I borrowed. I adjusted the airflow on my gun

Thanks for the advice guys..
It was heaps of work, but I finally got the cabinet sprayed black and it looks great

I read that it’s best to leave the cabin alone for a few days before starting the stencil work.. so I will start by giving it 4 days.

I do have some further questions in regards to stencils (pinball pimp), that I could not find an answer to on this forum.

1
how long can I leave the stencil on before painting? Can I apply it the night before I paint or do I risk damaging the topcoat if I leave the stencil on to long?

2
I find that many people put the cabin on its side and spray the stencil from the top down (horizontal). Is this better in regards to spraying or stencil removal?

If possible I would prefer to keep the cabin upright and apply my stencils to all 3 sides of the cabin and then spray 1 side, remove the stencil, followed by the other sides.

after spraying the first stencil, how long do I have to leave paint to dry/harden until I can start to apply the stencils for the second color of my artwork? I am using SPARTAN automotive finishes acrylic paint for all my paint work.
