I recently heard about a guy who was having problems with tools going rusty. They were stored in his van overnight so condensation forms on them each morning and he lives on a small island so the water vapour in the air is salt laden, making it more effective as an electolyte - one of the conditions needed for corrosion to occur. I contacted Paul Prince at Shield Technology who suggested the 'belt, braces and jockstrap approach' was called for, i.e. surface protection, contact corrosion inhibitors and VCI (airborne) protection - all in liberal measure.

I emailed Paul back suggesting that a huge VCI pot which would protect anything stored in a van would be a popular product - after all, how many tradesmen have vans? I lightheartedly suggested he could call it something like VanGuard. He said the concept wouldn't work as vans are too draughty and even if the pot were the size of a biscuit tin, a good stiff breeze would have all the corrosion inhibiting vapour drifting off down the street.

He did however come up with a new product which is the 'belt, braces and jockstrap approach' in a tin. It has a viscous high quality mineral oil base so it will provide barrier protection, plus it has both ferrous and yellow metal corrosion inhibitors and a VCI additive, so your treated tools act as VCI emitters themselves, if you miss a spot then the VCI chemical will condense on it and prevent the water vapour from acting. Wipe it on with a rag and store your tools in a sealed box so the VCI element can do it's thing.

To my great surprise he kept the name! Shield Technology VanGuard in 125ml and 250ml tins is now available on the website!


  1. Hi Matthew - something's happened! I seem to be able to post comments - Rob

  2. I thought the Americans called 'vans' Panel-trucks'!

    VanGuard is a good name in the UK though. Except who would leave tools in a van in this country? I wouldn't. Not even in the back yard of a Police Station!

    But this stuff should work in a workshop too. So I think I'll get me some asap.
