The word "patina" as i understand means natural tarnish or natural discoloration.It occurs mainly on metals due to its composition & exposure (others could elaborate) and sometimes on different types of glass.We should not confuse ourselves with old handling-stains,oils & dust layers(grime)against rust & rots on bare metals.I used this term "patina" as "follow-up" to others having used it inappropriately but i was wrong to have continued in the first place and for this i say that im sorry.
Rust is no patina but just that.Metal rust is not a naturally occurring phenomenon but a composition & environmental one yet some could oppose this.Also dirt,dust,nicotine & grime on our Lesney castings is no patina and should/could be carefully cleaned away/removed if one knows how to do it with no rocket science required and without dilemma too.One would never see a highly collectible 1960's Ferrari Dino appearing in a classic car show with its "original patina".It just doesn't happen.Why?...because its a rare investment collectible and had to be taken care of and protected from/against the harsh environmental effects,accidents,rust & rot.
Why do people damp-seal their house walls,Corrosolve their cars(spraying Tectyl),fill engine anti-freeze,grease the wheel-bearings,pulleys,joints & ball-joints,door jams & hinges,apply copper-slip on bolt threads,why do they oil-treat & varnish bare furniture or most types of exposed wood,etc,etc,.Do we call this tampering and going against OE Mnfg specs? Answer is a simple NO but mostly a preventative measure for protection & longevity which inadvertently is your investment protection.
Would one knowingly live near a chemical plant or leave his car parked nearby whether prized or other for a long period of time? Why will the the answer be a definite NO? There are constant vapours (salts or chemical) in every home whether living on the coast or inland.Even temperature controlled rooms are exposed to vapours.
Dad & I are both coin collectors and we know how to "clean" and conserve coins & remedy certain defects without any tampering and without any other experts noticing or condemning any.Almost anything can be cleaned or given new life if one attempts and knows HOW NEVER TO RUIN IT.Generally some people say they cannot do things or that it cannot be done but to me they are just purely not interested in any attempts or plain lazy or cannot apply basic common sense which is not so common after all.
@ Kwakers,Applying a simple oil treatment does not in any way mean tampering with any mechanical or structural elements and cannot see how its value would be "threatened" esp if the process can be immediately reversed if desired.No chemicals,rubbing,sanding,alterations etc is taking place here.
Hypothetically,do any of our shiny-mint models whether ultra-rare or common require patina to authenticate its origin.Are u saying that all clean models with factory-clean axles would be treated or scrutinized as though they were fakes? Is their value gonna be affected by this? Should we purposefully neglect it so as to welcome rust & rot "patina" or should we have to take the common-sense exacting approach of care? Rust is welcome nowhere as far as im concerned.
Rusting & eventual rot is in layman terms is caused in this sequence ie:tarnish,oxidation,rust dust,corrosion,decomposition/degradation/crusting,eventual rot and demise.I had seen rot on axles that was so bad that when Dad tried turning the wheel it simply broke off in his hand and that was the end of one of the rare castings that we all would have wanted in our displays.Wait for it......a #50 John Deere Tractor with the #39 Ford Tractor rear wheels.That YPH actually bonded to the axle-end which rotted away causing this loss not only financial but loss of Matchbox history for the future generation of collectors.Bad things (detriments) happen out of intentional neglect.
For what its worth and as i mentioned earlier that Kurt or anybody on here really doesn't have to use this remedy that i mentioned although taking early preventative measures is better than the cure and blatant losses.
I certainly would not argue that we are all different in the ways we think and do things.
Hope i didn't bore u all....
