To prime or not to prime

Hi All,
I know there has been a lot of discusion about different procedures in how to paint commando barrels. but I am a bit confused about whether the barrel needs to be primed with a suitable primer after they are stripped of old paint and blasted with glass bead blasting. and then painted with black paint.
Does the barrell really need to be painted with heat-proof paint or not?

Also is it best to paint the barrel after they have been rebored if needed?

Thanks for your opinions.

Personally, I just use a normal heat resistant paint and no primer, but I'm sure there will be some different opinions on this one? I have used ordinary enamel spray paint before now, and that was OK.

Brewer,
No need to prime iron barrels, but you must use a good quality heat resistant engine enamel. The barrels must be clean and dry. Apply several coats as per can instructions and if the barrels are off the bike, use the missus hair dryer to warm the barrels a bit before spraying and afterwards to assist the cure. Any AutoOne store will have a good brand and expect to pay about $14 for a can big enough to do a V8 block.

Ok, thanks guys. I have bought a can of HVT (PJ1) Engine Enamel paint. I will use that after the barrel has been glass bead blasted.

Thanks for all advice.

Hi. You are getting some great advice on barrel prep. Do not use your oven or your wife's oven mitts to "cure" the paint job. The vapors gagged even the cat and I had to buy new mitts! :twisted:
