The important thing is to build up the coats.
First flatten the surface to provide a key. Use 4000 - 6000 grade wet and dry paper. You don't need to remove all the paint.. just get in matt, so your primer will stick.
Primer - you want a grey or white primer. Build it up using about 6 coats in total, allowing plenty of time to let each coat dry. The primer coat should be the thickest.
When it's bone dry (the following weekend?) use some 8000 grade wet and dry paper to smooth it down. It should be silky smooth now and blemish free. Paint won't cover up any blemishes.. so if you can't get one out, use more primer on that area to cover it. Allow it to dryagain and repeat with the wet and dry paper.
Spray the beast silver. Use 2 or 3 really thin coats. so that it covers all the primer and isn't see-thru'.
It's not that simple to smooth metallic paint.. but while it's drying, invest in some T-cut or Rubbing compund from the Big H. You need to remove the pimples of paint that you'll be able to feel with your hand when you run it over the surface. Rubbing compound is essentially a coarse polish. You must let the paint dry thoroughly. Don't rub it too much or your primer coat will start to show through.
Lacquer is as above. Build up a good few coats, making sure it doesn't run. This is especially important now.
Finally when it's dry, use that 8000 wet and dry paper, followed by a touch of rubbing compound, followed by a very mild polish like Autoglym Super Resin polish. The beast should have a deep and lustrous shine..
