ACF-50 Saltwater protection

Like most people, I always like to look after my gear and make it last as long as possible. Especially the expensive bits of kit or those that are prone to corrosion :-

  • Cameras
  • Rods and reels
  • GPS and connectors
  • Fish finders – particularly connectors
  • Battery box/connectors


For most of these bits of kit it means a quick rinse under warm water after a kayak fishing trip. Some of the bits of kit get special attention – a smear of grease or Vaseline – and a spray with a moisture dispersing aerosol such as GT85 or WD40.

This is all very well and good, but most of that care washes away dirt and moisture – but doesn’t really stop the saltwater corrosion build-up which is so noticeable on electrical connectors eg. Fishfinder.

Then Andy Benham (Pugwash) from Anglers Afloat, told me about a spray called ACF-50. It is from the States, and was originally used in the Aerospace industry to stop corrosion from salt. It is now used by motor cyclists for the same reason. It works by spreading a thin film onto the surface of the object which protect it for up to a year. It is also recommended for use on electrical connections.

I ordered a can from eBay and have been using it – particularly on the connectors of my fishfinder.

I will let you know how I get on. But early indications look promising.
