The Ultimate Motorcycle Protection? ACF50 v XCP Rust Blocker

As I have mentioned, demonstrated (and used) I am a huge fan of ACF50 as the main protectant for my motorcycles.  I have been using it for many years and the results still impress me, and make sure any time I am asked ‘what should I use’ I can give and honestly mean a hearty recommendation to ACF50.

However, like all things, products can be improved upon (or worsen with revisions), can be changed, even new products can take an undisputed crown, and for that reason it is important to stay on top of any new developments in the market and keep an eye open for anything new that is making waves.

One such product at the moment seems to be… XCP PRofessional Rust Blocker.

So the big question is, ‘Is this the product to throw ACF50 of its throne?

On my search for comparisons I found one site that had conducted a nice experiment between ACF50 and XCP PRofessional Rust Blocker and they have kindly allowed me to link directly to that blog post :

My test is as follows.

Apply saturated salt solution using a fine mist, to a sample which is flat so the water sits on the surface, then leave to dry for 24 hours, apply again, repeat, occasionally swap to straight water, again allow to dry, repeat. This test mimics what really happens when you ride your pride and joy in the winter and don’t have time to thoroughly rinse off all the salt every time you park it up.

Two British Standard samples of fresh steel were degreased thoroughly and only handled with gloves to avoid any transfer of oils from my skin.

Both samples were then divided into two using tape.

The right hand side was treated with XCP Rust Blocker and the left side treated with ACF50.

The tape was then removed as a control area as it had no treatment of any product.

I used two samples to give the fairest results.

The first sample was treated with a much heavier coat of the product than the manufactures claim is required. 

The second sample was treated with a light coat of the products as specified by the manufacturers. 

ACF50 does not dry and XCP seem a little vague about the exact drying time, so both test samples were left for 14 days to dry. Any product that claims to dry, should be dry after 2 weeks.

So there we have it, I’ll let you make up your own mind, or carry out further research of your own.  Of course if you find anything else interesting please feel free to add it to the comments.

I am aware the XCP Rust Blocker product is relatively new on the market so as time goes on more experience and more users will come forward and we will get to see how the product is working with more bikes in the real world.  For me though, at this point I will placing another order for ACF50.
