Triumph Unit 650 cylinder block paint

[joe90]

Fairly simple question, has probably been asked before.  Can anyone suggest a diy product readily available in the UK for painting the cylinder block of a 1970 Triumph unit 650.  I do not have a spray gun but there seem to be a number of heat resistant spray can paints on the market.  Obviously stove enamelling would be best but have been told this can lead to overheating problems, also trying to keep cheap - spent an absolute fortune on renovation so far!!.  Should the finish be gloss or matt, presumably matt would give better heat dissipation.  Thanks

I have used Hammerite High Heat paint. Its a matt black  brush paint which resist's heat up to 600 degrees centigrade. Its a bit thin so you need to apply a lot of coats .
All the best goldy

Stove enamelling is the right way to go as it is a very thin coating of paint and will work out cheapest in the long run. Powder coating is incorrect as the idea is to dissipate the heat not keep it in!!

Thanks very much for the advice, that gives me something to think about.  Another question - any recomendation for treating aluminium casings after bead blasting - not the polished outer covers but the main crankcase and rocker boxes etc.

Just a light oiling with 3 in 1 oil, stops any white corrosion forming. I have all my cases vapour blasted which gives a slight "as new" sheen look.

AN OVER THE COUNTER SPRAY CAN OF BARBECUE PAINT FROM ANY HARDWARE OR DIY STORES WILL DO THE JOB. CHEAP AS WELL ! IT HAS STAYED ON MY VINTAGE CAST IRON BARREL FOR 7 YRS AND IS STILL OK.
