Is there a tip for cleaning the slightly oxidized aluminium trim around the doors etc

Any advice would be much appreciated.

This alli is anodized where it is dipped into acid that gives a hard skin on the outer surface, if T cut will not restore it, then not easy to know what to do.

I do not think the anodizing can be re done.

Auto Glym SRP is quite good at cleaning it up, failing that AutoSol but be careful as it is quite abrasive

Thanks for the tips, I tried an area with Metallic T-cut yesterday and it has improved it, but will also try the SRP after seeing it has a sealant which might help, sounds like good stuff will try it on the paint work as well.

Found some good info about SRP from a detailing website below:

Questions

What is Autoglym Super Resin Polish (SRP)?
SRP is probably one of the most popular products from Autoglym.
It is a lightly abbrasive polish with a lot of fillers and it also contains a light sealant.

What will the fillers do?
Fillers fill up swirls and light scratches for a certain amount of time. Since there is also a light sealant in SRP it means that it offers protection for maybe 1 or 2 months. The fillers will disolve after some time so each time you wash your car, more swirls will be visible. To keep that nice looking paint after when you just polished your car with SRP, you have to polish with SRP about 6 times a year.

How much correction does SRP offer?
The cuttingfactor from SRP between 0 to 10 would be 0,5 or 1. It isn't meant to offer real correction, although it gives a corrected look to your car when applied correctly.

How can you apply SRP?
SRP can be applied by hand, dual action polisher, random orbital polisher or rotary polisher.

How do you apply SRP by hand
You can apply SRP by hand using foam pads like Meguiar's Gold Class High Tech Applicator Pad, German Applicator, or any other foam applicator. Microfibre pads work too.
Apply a few Skittle sized blobs on your applicator and spread it on the paint. Work on areas which have the size of about half a door. Then work it really well untill it becomes a little hazy or clear. Then buff off with a microfibre towel.

How do you apply SRP by machine?
Use a light polishing or polishing pad. Apply a few Skittle sized blobs on your applicator and spread it on the paint. Work on areas which have the size of about half a door. Then work it really well untill it becomes a little hazy or clear. Then buff off with a microfibre towel.

Can you apply more layers of SRP
Yes you can. The more layers you give your car, the more swirls that will be filled. Up to 5 layers would work really good.

Does SRP needs to cure?
It's not necessary, but you can let it cure.

Can you use a glaze after SRP?
Yes, you can use a glaze after SRP.

Can you top SRP with a sealant and/or wax?
Yes, one of both or both works great. A really good sealant to top SRP with is Autoglym Extra Gloss Protection. A good wax after SRP is Autoglym High Definition Wax but any other wax will work fine, as long it won't contain cleaners since cleaners remove the fillers.

Can SRP leave scratches or marring?
No, but dirty applicators or too aggresive pads with the machine can.

How do you remove old SRP from the paint?
By polishing or claying the paint.

Can you use SRP on vinyl stickers?
Yes, you can. Don't apply it to harsh, but other than that it won't do damage.

Will SRP do a good job on faded colors?
SRP will do a great job on faded colors!

Can SRP be used on wheels?
SRP leaves a great finish on wheels, along to some protection against brake dust and road grime!

How to prevent dust with SRP?
Lightly spritz your pad with water or detailerspray. This will give the SRP a thinner coverage with less dust.
Also working the polish in for a few minutes until it's gone clear will result in very minimal residue to remove, and what there is won't come off 'dusty'.
