so I've seen bonnets stripped of paint down to the aluminium - looks great I think and is my next project

they state there isn't an issue with glare

I presume this is all OK just like the chrome wrap, anyone know of legal issues of doing this?

I don't recall any parts of the VSBs which relate:

I suppose if you change the colour of the car you may need to inform the road authority. Should be fine imho.

iI hope yours is 100000% dint free and there is no bog under the paint.

Correct me if I'm wrong but the alum bonnets are not your average fixable and need to be replaced rather than bogged over.

Being aluminium shouldn't change if it can be bogged or not, the alloy means it's harder to fix properly, but there's nothign stopping a person from slapping some bog on and painting over it.

It's just metal, it can be reshaped with a hammer and dolly like any other (in fact, alu would be easier since it's softer)

+1 Anything can be bogged over!

A paint stripped alu bonnet would look quite ordinary. You would need to polish it for any shine, and then it would tarnish quickly.
Just wrap it in chrome vinyl if you want the mirror look. Along with matt black, it is a passing fad.

The aluminium should stay un-marked for a fair while I would imagine.

My number plate bracket is aluminium L section from bunnings, and it hasn't tarnished or marked in the 8months or so it's been on the car.
Granted, I have no idea if the Bunnings stuff is coated with anything to protect it, but even the edges that I had to cut are still clean.


I always thought one of the strong points of aluminium was it's resistance to corrosion, oxidation, and tarnishing?

Maybe I'm only thinking of certain aluminium alloys though?

Your bracket is anodized clear.

What about the edges where I cut it with an angle grinder though?

They arent but they will corrode.

Al will tarnish a little, but not rust like other metals. I think polishing a bare Al bonnet would be no more work than cleaning the paint. I mean, you'd need some spray on metal cleaner rather than water. But I think it'd be doable.

Depends on the aluminium. But basically hks is right. Depends on how shiny you want it.

Aluminum oxidises very quickly but then stops once an oxidation film covers it. This film is kinda semi shiny (depending on the alloy composition.

Raw aluminium from Bunnings ect is not anodised clear. But a lot of it is designed for exposure so is a stable alloy.

Either way, a clear coat could be put off the bonnet after its been stripped back.
