Powder coating alloys - help please

[Meek_racing]

I'm having my alloys shot blast and powder coated on Monday at work. Is it only the bolt hole and chamfered face that need to be masked off or the rear boss face too?

I would do the rear also to ensure a flush fit to hub

Haha quality, your location spells my sirname! Ingham...

A light dusting over the rear is fine, or it's open to corrosion.

i have had a few wheels powder coated before. i never masked anything off though, had the full wheel done. then when i re fitted the wheels and tyres to the car they were fine for 1000's of miles.

Exactly, had 4 sets that have been Zero issue. There's a lot of BS surrounding powdercoating from people who either have no idea, or have a hidden agenda (business)

The wheel bolt holes will get chewed up anyway.

As above, I've had endless wheels powdercoated over the years, nothing is ever masked off.

All I would say is to give it 500 miles after fitting them and then just re-check the wheel nuts, then do so again another 500 miles later.
Before you know it the nuts would have cleared the powdercoat off in the nut recesses and all will be fine.

The only issue ivefound with not masking off the hub face of the wheel is if you use them on track or very heavy braking, the hub can heat up and melt the coating causing the wheel bolts to loosen as there is now a gap between the wheel and the hub.

Wheels will be used on a track only car which is where i've heard about this problem.

Don't go plastering it on the rear face, just a light dusting to prevent corrosion. If you're getting wheels up to a temp to melt powdercoat (bear in mind it's applied at 180-200C) then you're doing well.

i've seen wheels that have had the bolts come loose repeatedly due to the bolt holes being painted or powder coated. It doesn't come off as easy as you'd think, so i'd definitely mask the holes up
