Well, it's time to start thinking about how to recondition the iron barrel on my '74 MkIIA. I need to get the old black paint off. What's the best way? Bead blast? Paint stripper? Both? And what kind of paint should I use for the repaint?
 
I used the nastiest paint stripper I could find, coated it thickly and wrapped it in a plastic bag for 1/2 hour. Then hosed it off with the hose. Then bead blasted it and washed it with thinners.

I used POR 15 Black coat. I hope it's able to stand up to the temperature.

Regards Graeme.
 
Gday Huffer,
Im not far off from painting my barrels too. Ive been checking out paint in the land of Oz. I was recommended JP1 barrel paint but no longer available as it was bought out by VHT.
I see VHT has a gloss barrel paint that with stands 500 deg (bakes whilst in use) and sells for about $18 OZZY. VHT also sells a gloss black product for brake calipers($15 OZZY) that with stands 900 deg. and has a ceramic base which must be baked on for some hrs prior to use. I phoned VHT and got put through to the paint blender and he told me that a ceramic blend is a superior product! I asked why cheaper and said that the pricing dept. believes motorcycle paint commands a premium! Anyway Im going to buy a can of each and do some testing to see which is, in my belief the better product. I will paint a piece of steel with both products and compare finish, tuffness etc. Hope to have some results in about 2 weeks time if work allows? Ive used the VHT barrel paint before(Harley) and was happy with the results, but Im a compulsive tinkerer and I feel this I must do!

Regards Foxy
 
Thanks for the two replies from Daown Unduh. Foxy, please post your results with the ceramic paint, as I would be interested in such if it works for you.
 
I hope the ceramic paint helps dissipate the heat off the hot engine properly. It would be a bummer if it isolated the cylinders somehow hampering the cooling of the engine.
 
Gday Huffer,
well I purchased the two spray cans of VHT paint and tried the comparisons. Both have the exclusive Ceramic formula which "Quote" from the can says "increases heat dispersion to restore, maintain and protect component surfaces". May clear up the concern there Rennie. Disc Brakes Australia were the first to use this ceramic formula and have done so for some 20 years with great success. Now after painting and baking the one piece of steel, I cant see no differance in the two paints, both have the same nice gloss finish, withstand an oxy- acetylene flame for some time and it doesnt chip easily.Pretty tuff stuff! I dare say they are the one and same paint, just the label and marketing is different. Im happy with the results and will stick to it. Incidently, VHT is owned now by Sherwin Williams which is one of the largest paint manufacturers in U.S.A.
All I have to do now is seal up and carefully bead blast my barrels and paint away. I have my own oven ( keeps the OL,GIRL happy) ready to bake the paint at 200 deg F for 1 hour. Hopefully this is of some help to you and others.

regards FOXY
PS. I was told buy an 80 year old life time motorcycle fanatic that an Ariel 500 come out with a silverfrosted barell and procceded to seize up in the Australian heat.This went on for some time until someone painted the barrell black, bingo, no more seizures. The silver apparently wasnt allowing the heat radiate, tending to reflect the heat inwards instead of out. I know alot or most of the modern bikes are silver of some description and dont have problems, it may have been piston composition?
 
Withstands an oxy-acetylene flame. Now that's tough. I will likely give that paint a try. Thanks for the info, Foxy.

Ditto. I too am interested. I have used vht on exhaust manifolds with poor results as regards to rusting quickly. It was the higher temp stuff they produced about 10 years ago. I have used Blackcote. It is very durable stuff. Not sure about its temp tolorance though.
