A couple of questions:
1. Looking again the Ring kit (Amazon), it appears from the Q&As that the kit I was looking at is for water-based fluids/air con systems? I would want one for engine oil. Anybody know a suitable kit? cdsdorset, which one is yours?
2. Also, I guess goggles are needed, but is that for eye protection, or to enhance the glow of the dye?
