    Default Working with Leather

    Hi Roger,

    I've been checking and I can not find one leather cleaning or renovation specialist in my City possibly even in the country. There are only dry cleaners for garments or cleaning companies who will not treat the leather properly.

    What sort of training is needed to become a specialist, in your opinion? Would it be possible to operate a mobile business or is a workshop necessary for spraying, etc.

    I used to renovate car leather only, but lost faith in the products I used as they were not "fast" to the surface. They wore away so I don't really offer the service anymore. How well would your colours last on a car seat that is used everyday?

    A specialist in my opinion means that one will only provide leather related services both cleaning and restoration including repairs and refinishing in all segment of the leather industry.

    The leather service industry could be segmented as Auto, Commercial, Residential, Yacht, Aircraft, Garment, Bag, Equestrian and other leather Accessories.

    Knowing what product is available and its application is part of the training search.

    One has to stick to a system that one is most comfortable with – they are called it “matched product system”.

    This forum is a no nonsense technical forum.

    This shall be our technical backup for our entire hiccup.

    It is also for technical trouble shooting when things go wrong, where we miss a step.

    Post a picture, ask a question.

    In leather cleaning and restoration there is no short cut.

    We are both a technician, an artist and triple as a salesman.

    We will learn the wisdom of triple caution for every single action.

    It is easy just to spray but it is 7 times more difficult to remove them.

    If it is a wrong spray it may be 7 x 7 times more laborious to rectify them.

    I was alone in the past; tips were like trade secret; we do not have a forum like this to share our tips willingly, it has to be bought with a price.

    The samples I have come in a five gallon drums too, “take it or leave it”.

    Five samples so five drums, not suitable… what next... always waiting for heavy continuous downpour… for a good ratio mix. (In a far away country, here people called it the Far East).

    I have countless failure in my attempt to succeed in a project until now – the Leather Doctor® System.

    By hindsight I wish I could have done it differently now with Leather Doctor® System.

    I thought I was the best, my customer pay me well and we were happy and oblivious too.

    We thought that these were norms, until now.

    The various products I used in the past were thick like plastic, they crack when flex, peels with poor adhesion, the solvent makes you "high", the cloudiness when moisture were trap between the tip of the nozzle and the object of spray using solvent topcoats.

    What more, the repair like putting putty or stucco on a crack will just crack again too soon, unless they are put in museum for display only “see no touch”.

    Well, the repair by heat iron, I never knew that heat could dry up the fatliquor; the supplier did not say that.

    Using heat that shrink the leather on every repair, kills the leather without replenishing the original fatliquor that provides softness and strength.

    Any more, yes of course color that fades too easily; they are not high performance against UV.

    Well again every color mix before application need to be tediously filtered otherwise micro color lumps will be spew out of the spray gun.

    Colors that stick on leather will peel on vinyl panels.

    And colors that sticks on vinyl looks vinyl on leather.

    Final result all feel and smell like vinyl.

    With Leather Doctor® System, these are things of the past.

    This system is 75% delivered 25% for us to mess it up and it will fail too!

    The next training is to practice on them.

    Until you make enough mistake during the practice.

    You will have no mistake to sell to your customer.

    Your customer will become your client and your cheer leaders too by and by.

    That why we don’t see many of these people around in every City or even in every Country yet!

    Auto or Car Seat System – Relevant Products and understanding them is part of the training in theory too!

    Its real until you practice on them.

    Do you think seriously that with Leather Doctor® System the color will wear away easily?

    Maybe I may have to answer in more details for better satisfaction in the next post.

    Hello Roger,

    Your above detailed explanation to Brian is great !! Thank you for educating us !!

    As requested in my previous message, do you have any leather workshop for actual trial ? I'm interested to join as I also have plans of setting my own Leather bag cleaning shop in the next few months.

    Do you also have any Asian branch that distributes your porducts ?

    Do you also have an Asian office where you conduct the actual cleaning, restoring leathers ? I'm sorry for sounding like a broken record. I am just very, very curious.. ^_^
