I too experimented with spraying, and I think your downfall is going to be the small compressor.

I sprayed some and it turned out good, but my small compressor 2.5 hp,30 gallons couldnt keep up and so after a few passes I would start to get weak spray and "spittle" from the gun since the pressure was dropping.

I would definatly practice on a hood or something and see if you really like how it turns out. DONT use acetone as recommended. I tried and it flashed hazy since acetone evaporates in like 2 seconds, use mineral spirits.

Curious to see what size compressor MyBUICK used.
