is there a way to achieve a nice looking paint job with rattle cans in my interior ?

LOL, I read that whole thread. Good one!

For the under the windshield in front of the dashpad its not a good idea to use gloss paint, or so I've read.
I used the HF purple gun at $10 to shoot rustolium semigloss black (actually a mix of gloss and flat) on inner fenders and it looks perfect. Did it in the back yard so it was not a high dollar op.
You can snag a craigslist compressor for cheap--hell--I have an extra in DFW. For cheap paint let the compressor fill and cool for an hour the first time, thin the paint, practice. Then start over but change practice to shoot in the last sentence.
There are vids about adjusting the purple gun to work better, as well as how to spray paint, pressure, volume, fan, etc. For example, start at ~12" from the surface and use long horizontal strokes. Lots of people spray in circles and get bad results.

If down to bare metal I have found that an etching primer like Cromax works good. I got it a body shop supply store.

I have found that if I try and use more than about 2 rattle cans in a short time it wears out my index finger. A spray gun trigger is much easier for me. I would just purchase a cheap HF spray gun and find a cheap compressor. When you are done you can likely sell the compressor.
