Vinegeroon And Motorcycle Seats

[robs456]

the leather hadn't been washed and neutralised and there was still some ferric sulphide salts left in it, which bled out and came into contact with something containing tannin and turned it black.

That's my bet. It was neutralised but probably not washed good enough making the black solution bleed later.

My point though is that however it happens people need to realise 'roon isn't a 'fire and forget' kinda thing, and need to handle it correctly.

I finish leather for commercial purposes and have discovered over the years that leather needs to be sealed if you don't want the finish rubbing off.

We have a "SATRA Finish Rub Fastness Tester" and have produced leather that will take 10,000 rubs.

The finish is a base coat of black resin and a top coat of black polyurethane resin, both with crosslinker.

It's probably overkill for a knife sheath or belt, but in our business we need durability.

I had a roon seat I made and used for a couple of years no rub off, also had a few belts and holsters with no rub off. I did the usual roon/baking soda wash/rinse/neatsfoot oil/rub with snoseal or my  own mix of wax/oil. Never had an issue.
