AJ,
If you already have some, paint a scrap model or a tin can or something and give it a try - or better yet, go to your local auto parts store and buy polishes or waxes designed specifically for car paints - I use a lot of automotive acrylics in painting my 1/24 scale autos, and these polishes and waxes work a treat - wet look glosses are easy to achieve.
I use these because I've not yet gone out and purchased the Millennium polishing pad system or the other sets on the market.
I just stick with what I know and what works for me...........
Cheers
