I suspect lanocote sets moderately hard, and later can crack
Its lanolin,a oil, no it doesnt.
high impact, high temp, Waxes, greases that have high molecular chains and are made to flow/ be flexable with other low temp solvents oils to apply (paint or spray.) dry out and go hard and crack
Bossco is very correct.. surfaces must be clean and dry 1st, its about adherence of the product, and note having ANYTHING underneath to be trapped and cause contamination of the product or how the product molecules bind.
Even saltway may leave deposits that are not comparable with the product being applied.
Also a little caution.. these products maybe good around a lot of protected marine areas.. under engine cowling, enclosed switch board applications. Apply to say vehicle engine bay type place, where dust accumulates, builds up on each application...you end up with a conductive coating over even into electrical wires and connections.
Not an uncommon situation when well intentioned just of wire moisture protection products used in vehicle engine bays after excessive or long term use. eg HT lead , distributer caps, leaking HT spark plug boots and feed back tracking in circuits. Also stored vechilce batteries going flat due to tops not clean or dust in the protective well intentioned protective products.
Whatever product, use very sparingly and only when need to.
If do have problems, chances are further application will only enhance the problem.
The reason I stick to lanlion long term is I know the compounds and properties of the product. Products that dont tell me what they are, I steer clear of where ever possible.
