I’m a big fan of the French product, Owatrol Oil, which is a superb paint conditioner and rust inhibitor.

Its versatility is its strength and it can be used as a standalone product or added to gloss paint which gives it a Downing Street-style mirror-like shine, helping the paint to flow beautifully.

As a rust inhibitor, it’s one of the very best, penetrating the rusted surface, driving out moisture and air and is ideal for use on chassis as well as machinery, engine parts, trailers and tanks.

Oh, and if you condition paint with it, Owatrol Oil prevents peeling.

Various sizes are available with a 1-litre tin offering great value at £27.23 inc VAT.
