Reliable and superior rust protection.
At this price and ease of application, this spray along with the brush on product are one of the best rust proofing products on the market, and has proved far superior in the protection offered than many of the other well known products.

Way better than ACF 50!
Now an XCP convert! No more ACF 50 for me!!! ACF is messy and gloopy! Your ACF bottle gums up and stops spraying! This stuff goes on and then sets as a film which stays there! You can even wash the surface dirt straight off without impacting the film! Totally stopped surface rust and salt corrosion for my bike during the winter! I ride 20K miles per year - so I am not a fair weather biker!

Does the job
The only thing I dislike is the look of it after application to the metal its protecting, it looks yellow and picks up a hell of a lot of debris, BUT, it really does stop the rust! I will use again; making chrome metal look yellow, is much better than rust.

Great
Leaves a tacky residue but it clings to the surfaces brilliantly. Can use it on black plastics as well to bring back their shine. Haven't had any issues where I've applied it, does come out quite thick but a little goes a long way. For certain areas I spray a bit on a rag and rub/dab it where I need it.

It does what it says
I have struggled for years to keep metal holders in the bathroom rust free, until I came across this product. It needs to be sprayed in well ventilated area and left to dry for at least 3 days or more. So far has been 6 weeks since product was applied to metal objects, no rust in sight, hooray!!

Works a treat
Great stuff works brilliantly, but the can stopped spraying less than a quarter of the way through the can contents. No good if it won't come out.
