Aluminum Radiator Finish

[Lamadogg]

Just purchased a 26-in. aluminum radiator from Year One for my ‘69 RR. I would like to keep the ‘natural’ aluminum finish. Can I simply install without painting or coating? Will the aluminum surfer any oxidation if I don’t paint or coat the metal? Thanks.

Most aluminum radiators are finished
with a Nyalic coating, which is a
flexible hard-coat resin. Should be
good to go unless you spill any
strong acids on the surface.
Dissimilar metal contact can occur
if using steel bolts/washers and
they wear this coating away. Which
is why most aluminum radiators
are set into rubber lined brackets.
They also help to reduce flex and
vibration.
