Rob,
I have used Steve's service many, many times over the past 10-12 years, not only to do boosters, but to also do Silver Cad plating and Gold Cad plating. His work is absolutely outstanding. The boosters are top quality in appearance and performance (the most important part) and he stand behind everything he does. You won't be disappointed. Almost forgot, he also does the hood hinges in Gray Phosphate. Visit his website at
