Corrosion Block

Further To my visit to the Boat Show on Monday the 14 Jan 2008 I had the good fortune to visit the Corrosion Block Stand where I got a 5FL.OZ container of fluid penetrate/lubricates & Protects.

It is with great pleasure that I am able to report on the penetrating properties of this fluid. One of my winter jobs is to free the stanchions (Stainless steel) from their bases (cast Aluminiumalloy) this is a good example of poor selection of materials and a real headache to get apart, having removed them from the boat. Having spent some time considering what might penetrate this structure and have on various examples (8 each side of boat) tried some to include petrol, lime scale remover, & cola with little effect the use of this fluid I consider a major contribution to dismantling in say hours rather
than days

I wish to pass on the excellent results achieved due to the application of Corrosion Block grease and Corrosion Block spray in marine maintenance applications (besides our general workshop use).

As you will be well aware the salt water environment is very taxing on water craft and Norfolk Island is no exception.

With a number of jet skis all being brought onto the island around the same time, it has been extremely noticeable the difference between the skis that have had regular CB treatment compared to those that have not. This is not only noticeable with regular spraying of the jet skis but very evident when CB grease has been used during the reassembly of the carburettors. Any jet ski technician would know, the carbs can give a lot of trouble and require a lot of labour when they wont come apart. Also the CB grease works really well when smeared on the atmospheric side of the diaphragm cover, as this always gets a corrosion and salt build up.

We also have very satisfied outboard motor customers that regularly spray their engines after use keeping their investment like new. When servicing the outboard motors and pulling the power head and cylinder head bolts out for cleaning off the corrosion, where CB grease has previously been used the results can only be described as fantastic. NO corrosion build up on bolts and easily removed 1-2 years later. Another great result from CB grease use. We also apply it to the manual steering cable when it is being refitted into the outboard. We haven’t found another product that doesn’t tend to seize the steering cable with lack of regular use with the exception of your CB grease.

You may pass this information on to other marine service facilities if you wish.

Corrosion Block

It's that time of year!
Well for most users of rigid hull inflatable boats it's the time of year to be thinking about winterising the boat and engine. One product I feel you should seriously take a look at is this professional corrosion inhibitor, which is relatively new on the UK marine scene.

At this year's professional boat show SeaWork earlier in the year, I came across this product which claimed outright that it 'killed corrosion on contact'. Quite a profound statement which intrigued me. As we all know saltwater can shorten the life and destroy our RIB's electrical wiring and also quickly make the spark plugs in the engine block solid due no doubt to our perfect climate for ensuring rapid corrosion on our beloved boats.

Dave Heppell, from Adams Aviation, has been so impressed with the product that his company has started to import it from the states. Initially targeted for the aviation maintenance and repair industry the product meets all relevant aviation authority approvals for use on private and commercial aircraft. Uniquely coloured blue it comes as both a grease for mechanical contact parts, and an aerosol for electrical wiring and as a penetrant.

I obtained some grease and aerosol and have recently taken the opportunity to use both products during the winterisation of my little Zodiac Mk II GT runabout, fitted with an old but reliable Mariner 25hp. Firstly I used the grease on all linkages and then in my grease gun for all the various nipple points. The aerosol was used to cover the electrical wiring and was also sprayed around the spark plugs. My first impression was very positive, to touch the product is very reassuring, it's clean and silky smooth for a start and one can appreciate the claims that it will stop existing corrosion, prevent new forming and is slow to deteriorate (it has a 12 to 18 month active life). It's use on boat brightwork was also advocated as it puts an invisable protective coat on all items it comes into contact with.

It's a very efficient penetrant, without loosening structural attachments and an excellent lubricant, without having any wax, silicon or Teflon additives (which actually seal in moisture thereby aggravating and perpetuating the corrosion process).

I'll have to wait until next season to see how it has performed overall but I'm confident enough to use it and I'm sure it will not disappoint. Before I used it however I tested, in a non technical way I must say, on a very old pair of garden secateurs. These were one of those favourite items, but had seized solid with years of sticky plant sap, surface rusting from being left out in the rain, and were destined for the bin. After a good soaking using the aerosol spray, left for five minutes, then wiped clean with a cloth, bingo! A fully restored quality pair of secateurs back in business. This certainly gave me lots of brownie points with the other half who does all the gardening as I have little time for that when one loves boating! And it saved me £20 for a replacement pair, leaving more to spend on the boat. Great!
