I will post also in Motoring.
I have a Moto-Lita steering wheel on my Triumph Spitfire which is wooden over an alloy core joined with alloy rivets.
A few years ago I refurbished it back to the wood, stained it walnut and Ronseal varnishrd it with 5 coats. It came up well other than the varnished alloy bits were golden in colour.
I did it again a couple of years back after being assured the "crystal clear" varnish I used was just that. Again a good 4 coat finish but still golden bright parts, though not so marked.
All the new wheels I see have totally silver rivets and rims. What varnish or laquer can I use to do it again, that will really be clear?
Moto-Lita could not advise me as "The oil based solvents and compounds we use are not available to the public"
