If you want to paint a base black, I would recommend using a good quality flat latex paint. Use just a paint brush. Unless you have equipment to spray paint, it is difficult to make a nice finish when using gloss black paint, - either in latex or oil. You will find attached my first Bottlehead kit: a Crack. It is finished with flat latex. If it gets scratched [or bruised], it just takes a minute or two to re-apply a quick drying latex.
When I did my Paramounts and Bee-Pre, I finished the bases in Pimento Wood Burl veneer. That is a lot more work, but the results are great, - if I humbly may say so. If anyone is interested, I shall be happy to advise on how to do that process.
