spraying Zero Rust (thinned per directions) with a detail HVLP gun? My compressor only puts out [email protected] and [email protected] Most of the detail guns I've seen require somewhere between 3-4CFM @40PSI. Is this a bad idea? I'm getting ready to paint the engine bay to look good, and I'm afraid that using a brush won't turn out right (after seeing the results on the cowl section). Also, what size tip should be used? They come anywhere from 1.0 to 1.7. Comments please.
