Powder coating - Aurum / Vaz / Armourtex / Respray gallery

i've copied and pasted this from another thread cos this is relevant for this thread too - Basically, i'm doing a custom paint job. the hubs im wanting to paint are chrome, do i need to use paintstripper or something similar to get the finish off or can i just spray paint straight on top?

Are the hubs chrome? or are they alloy? if they are chrome then blast over them with a metal pan scourer, and then some wet and dry...you have to scratch up the chrome, and to get into the corners the pan scourer will be easier, then if you can get the soft sanding blocks from a hardware store they are good to...the chrome needs to look hazy if the paint is going to stay on for more than 3-4 months without chipping.
you can then use a primer and a top coat, after you have primed them leave then a day or two and for the next couple of days 'cook' them slightly with a hair dryer.
'dry flat' them back (also known as nibbing) and then you can apply topcoat.

always do two or three thin coats, rather than one thick...

if the hubs are alloy, then you do the same however ideally you will need an etch primer, as the alloy doesn't like the paint and they will flake sooner.

Cheap refinishing merchants, will sell you the etch primer and the sanding blocks, use a mask with etch as it's poisonous and use gloves as it's acid based...

or if you don't want them to last for ever...molotov.
