I live in a seaside community where I CANNOT have my cycling gear deteriorate rapidly due to sea salt in the air.
I used this product on my newly-installed Yakima Roof Rack, lock cores, overhead bike rack and cargo box's stainless steel parts.
It STOPPED already-growing rust on a newly-installed product, DEAD in it's tracks. A little rust smut easily disappeared...
I like the UV indicator, so you can visibly see where you've been with the product and what you've missed.
If you have a roof rack or want to protect your bike,...this is IT!
