my paint is the same, thats why im doing a bit of testing with the aerosol paint (also on tight budget)
i went to a specialist auto paint shop (spetrum auto paints [in tassie]) i got them to mix me up the same color as my car from its color code (rhone green) , they did a great job on matching the color. took them about 10-15 minutes and cost about $25 per can and $10 for clear coat so i got 2 of each. (you will have to find out if the paint can go over the top of old paint [after uve sanded it of course] or whether you have to rub it right back to metal and use primer aswell)
acrylic based paints
it took about 1 can of color to do a group 3 bonnet scoop (about a third of a bonnet as far as surface area goes) and 2 cans of clear coat (dont skimp on the clear coat, i did about 5-7)
i havent given it a rub back with wet and dry to get rid of the orange peel effect yet, but it looks great and very shiny so far. i did the grill on my VH today and that looks pretty good too, the most important thing is to take your time and dont rush it, i spent about 2 days doing the bonnet scoop in the shed (mostly waiting for drying time), remember over estimate your drying time, i gave it double what it said on the can because i live in tasmania, has to wait for a warmish day and put on the heater aswell
any scratches or anything will show up in the paint unless you use a really fine sand paper
i am by no means an expert and this is my first time painting with auto paint, but i just did my research and did some practice and got pretty good results. if you have any more questions dont be afraid to ask
