Filler for Alloys? Damage question! ?

[5509433]

Hi all,

I will be going through a stage of refurbing some alloys soon. I plan on getting them shot blasted and then powder coated.

A few of the wheels have kurbing and also chunks taken from the face.

What is the best filler to use (when necessary) for shot blasting?

I don't want to make the wheels look perfect, and come shot blasting, have them destroy the filler!
When you pay professionals, what do they use to overcome such damage?

If they're being blasted, the only thing that will stay on is alloy welding.

Blasting will remove all trace of any type of filler

So I'll need to get them sorted professionally then?
Dammit. I suppose it will save me money if I do the majority of the sanding on scratches?

If your having them blasted, don;t waste your time sanding anything.

I did think that, but what about the deeper marks that can be sorted by hand? Around the edges and such.

Blasting will remove almost anything. How bad are the wheels? Any photos?

I'll get some photos later when I go home for lunch.

Thanks guys!

Photos of some damage.

I wouldn't do anything with them if they're getting blasted and powder coated

Really? The second picture shows the wheel out of shape?

I was going to clean them before powder coating, but them realised that shot blasting is the cleaning process...doh!

Will the shot blasting correct all curbing and other dents and damage? I don't see how it will cure dents, and the part of the rim that is out of shape.

Been searching around. And I have come across this..

Allows for powder coating to be applied?

When I gashed, yes I said gashed, my old Rs7's I used Etech puty. Comes in a refurb kit. Was spot on and blended with original alloy well.

It would probably be better if you could do the filling/sanding after the shot blasting but before the powder coat. Shot blasting will not magically fix the damage, it'll simply clean the whole wheel. If you then powder coat chances are that damage may show through.

That alloy wheel filler would be fine prior to powder coat, but the powder coat will be so much better if the wheel can get shot blasted first.

Ok sweet. I was worried about the powder coating not sticking to the filler. I'll see what I can do. Thanks for the help!

For powder coat to stick to the filler, you'll need to use a filler thats capable of holding an electrical charge (i.e. a metal based filler)

If you see the link from alloy paints. It states that it is fine for powder coating. I shall drop them an email.

Ok. Went to the coaters today. Showed him the pictures. I mentioned about the filler, and he said as long as it is a metal filler, it will be fine.

Of the other hand, I did some more research and came across braising. I may give that ago. Undecided.

Another question.
When people have used standard filler as they are only painting them, when it comes to getting the tyres installed, has the filler ever been damaged?

I've used 'Metalik' before with some success. Availble from halfords, mix the hardener into the paste in a pea:golf ball ratio.

Just be sure to be quick, i'd say you get about 5 mins max before it starts to dry and becomes hard to apply.
