Now that opened a can o worms init. . :wink:
Why not just make them with better plating in the first place
I think you will find out the Brian (grump) has been fighting this corner single handed and challenging the manufacturers that's why we have suppliers such as Dan coming in with different kits.
To be honest, you, Joe bloggs and me, joe's brother Fred would not be able to test the so called "up-grade" plating thickness nd actual metal quality.
That would need expensive testing gear and an investment that would need a decent lottery win to finance.
I general we all have to believe what the suppliers advertise the wares at, up-grade gold means just that, it's usually a thicker plating meanin it won't wear out as quick..
The gold plating is not as hard wearing, hence you usually get the gold that's up-grade but I see some of the other kits such as chrome are creeping now. I can see Brian reading this now and biting his tongue. .
Sure he will be along soo and give his four Penorth.
