Mike, Here is the formula for Brewester Green. This is on a 1 pint can of touchup paint. If you take it to an automotive paint store they will be able to make you a sample to be sure it is what you want. In fact if the store as been in business for many years they may even have the Brewester Green in their files. This is where the formula on my can came from. The numbers on the lid is the mixing plan: (3 parts paint, 1 part Hardner, 1/2 part Reducer)
I have a spare set of motor shields. They need a little work but are very serviceable. Send me a PM if interested. Harold
