Firstly, powder coating is a process like electroplating and not a product.
So you can get cheap vinal powder coating like on thoes cheap cloths airers or outdoor funrature that breaks down in less than  6 months.
Or you can get the metallic oxide powder coating they put on fuel boosters of rockets and anything in between including full vitrious  baked enamel as on your bath tub.

Secondly again I go for POR 15 on hubs.
The chassis coat will never peel flake or rub off provided you remember to top coat it and do the preperation properly.
So it is a once ever job, never to be done again.

That is really interesting, I had no idea. Wish I'd known this when I was flaffing around with my hubs as I would much prefer a tough coating than the nitro I ended up using.
Good info.

I have read that if you get car wheels powder coated it is wise to remove the coating around the wheel stud hole as the nuts may come loose when the wheel heats up and softens the coating.

I forgot this advice when I had the barrels and rocker boxes of my BSA Trike powder coated. After a couple of miles driving the engine started to loose power dramatically and I just managed to limp to a local garage.
On lifting the bonnet I could see that the pushrod was not just operating the rocker (sometimes exposed rockers are useful) but in fact the whole rocker box was being pushed up and down. I had forgotten to clean the powder coat from the underside face of the rocker boxex and top of the barrel where they wewre bolted and the nuts had come loose.

The barrels still look OK except around the spark plug holes where there is not rust as if the coating has burnt off or was too thinly applied.

I have seen an A10 (Catalina style) with powder coated barrels that gets everyone crowding round to look at the 'ally' barrels!
Never tell people your troubles. Half of them are not interested and the other half are glad you're getting what's coming to you.
