Re: Paint suggestions
As was stated, you won't be able to get a thick flake finish due to the limitations of the aerosol nozzle. But you can get some nice metal flake finishes though, and if you use a regular silver basecoat it'll add more brightness and overall depth to your finish.
As far as spraying the edges to get your burst, there are a number of ways to do it, and personally I've only ever sprayed one burst style and it was with spray cans. I traced the body onto an old cereal box then I redrew inside the lines to reduce the overall size, leaving about 2" around the body.
I basically used it as a hand held paint mask so I could keep my burst consistant.
I've read somewhere that guys will trace the body like I said, but they will push thumb tacks into it from the bottom side so it is raised above the body because they lay it on the body as opposed to holding it like I did.
The one biggest tip I can give you there is to spray it head on so you don't inadvertantly get paint "under" the tracing, so try not to paint it from the side.
I'd practice with a 1:1 scale 1dimensional cardboard cutout and a corresponding tracing to either lay on the body or hand held.. Practice spraying that and getting your can angle right so you know where to spray and where not to spray.
I only stress that because metalflake is a pain to spray so try to get your coats even and consistent cause it'll basically be a one shot deal. Also it runs a lot easier, so try to go with thinner coats than you typically would. Plus thin coats dry faster and that'll be a gig help.
