Hi MikeyH
No problem at all. I've still got a tin in the garage (not sure why as it's virtually empty

)
It doesn't actually say Silver on the tin, just 'Alloy Wheel Paint' and it has a silver cap.
There is a code on the tin: ATOOALW500 (the 'O's') after AT could be zero's but they are larger than the 500 ones.

A VOC number: 2004/42/11B(e)(840)651
Also a company Tel No: 0161 6270101
There is a barcode serial number, but assume that's not much use to you?
For the primer I used Autotex's.
They had 2 types, 1 for alloy wheels and 1 for steel wheels. IIRC the one for steel wheels had better 'etching properties' according to the guy in the shop.
Hope that helps
Steve
