Anti corrosion ?

(1/2) > >>

Tokumeino:
Hi, not sure whether this matters a lot or not but websites such as All City's advertise anti-corrosion treatment :


--- Quote ---In Electrophoretic Deposition, or E.D., coating the frame or fork is placed in a paint bath where an electric charge is applied. This fuses a thin layer of black satin coating to the tubes inside and out. This coating acts as both a rust preventative inside and a primer out.

I think that Soma frames also start to include such a coating.

Is there such a thing with Thorn frames ?

David Simpson:
I believe the workshop prep includes the coating.

Edit: This is a spray-in coating. You may be referring to some electrolysis coating?

I bought my Sherpa frame used.  The previous owner told me that he applied Frame Saver to it.

I bought my Nomad new, I put Frame Saver in all the tubes that I could.

I do not know if you can buy it in France, this is what I used.

There may be other products like it.  I have also heard of people putting linseed oil in frames to coat the inner tubing.

I do not know if it really did anything, but I felt better that I had done something to help reduce corrosion from occurring.

Linseed is a drying oil, a very hardy painter's medium, 100 years plus of protection. Natural volatile elements evaporate and would leave a thin, very even wax-like layer inside the tubes. Can't do any harm. To my mind superior to cheap wax of unknown origin and composition mixed with petroleum derivatives, which is what most 'frame protestors' are. Walnut oil, available at the supermarket, is also a good choice for the same reasons as linseed oil.

mickeg:
If you have never used linseed oil before, if you have any linseed oil soaked rags when you are done, they can spontaneously combust.  Google it for more info.  Be safe.
