Paint for radiator.

[Mick Hobday]

Can anyone recommend a suitable paint for the radiator core on my 1932 Tourer?  Thanks.

This is the stuff I use.

Hmm, not too sure about the 3-4 coats the article mentions. The radiator guys I dealt with [albeit on 'moderns'] blew a well thinned single coat of paint over the core. Never made a note of the product, and it was probably proprietary,  but it smelt as if it had a very high VOC content, certainly it dried very quickly and looked to have good coverage. Maybe ask your local radiator repairer?

I used Halfords Matt black, seems ok to me.

+1 for Halfords Matt Black spray. I think it's an acrylic based paint.

There is a matt/satin finish black product called "pot black" sold by motor bike shops etc, intended for engine barrels and such. I use it on the head and block. It dries quickly without leaving brush marks. No good for exhaust manifolds but ok for other bits subjected to reasonably hot temperature.

Try Hammerite HIGH HEAT in Matt Balacck - designed for woodburners and such.  A quick dusting over is all it takes - dries almost instantly on contact and looks 'right'.

Thank you for the suggestions. I thought there might be a paint specifically for radiators, in fact I see there are some with Frost Restoration but they're out of stock. I suspect they're regular high temp paints repackaged as rad paints anyway1
I'll go with a heat resistant matt black aerosol.

I just squirt some 'Tough Paint' satin enamel at it if it's looking a bit tatty.

Aldi matt black stove spray can, £3:99.
Did mine 8 or so years ago and has never flaked.
