If it's silver you will probably need a 2-stage clear-on-base process. I think most sprayers still use 2-k for the laquer which is bad stuff, I have used a 1-pack laquer but it gives you a satin finish that atkes a lot of polishing to a shine. Also clear-on-base can peel after a while if you don't prepare well before the laquer.
With the price of paint these days I doubt you'll get a decent job for cheaps, ours cost £1,800 or thereabouts to respray in 2-k solid red.
