So CarPro has announced they are going to start shipping there products with a new style sprayer head, similar to the tolco ones but black. I was looking in to getting some tolco sprayers since I bought 12 CarPro bullet bottles with sprayers and the sprayers leak quite a bit. What’s the difference between the grey ones and the black and gold ones? The sprayer that leaks the most is the one that hold nanoskin speedy brite organic wheel and tire acid cleaner. Will the grey ones hold up to that? Or should I get a black and gold for that stuff? The black and gold one recommend not using with other solvents? Very confusing on which one I should get. I’d like them all to be the same.
