    depends if you are stripping the existing paint right back - or not. ie, are you blasting or sanding them?

    Its basically the same as any other bodywork...

      Sorry should've mentioned. They're completely stripped of old paint. Don't know which primers to best use for bare aluminium as more you read more opinions you find.

        The first layer down has to be acid etch primer or your grey primer and therefore top coat will peel off. I like epoxy paints both primer and top coat, they are tough and seal totally against moisture which will lead to corrosion. I did my wheels with etch, prime, silver and lacquer about 8-9 years ago and apart from where chips/scuffs have appeared, the finish is still spot on. If you can spray two pack with spray gun then do - harder and more durable than rattle cans.

          How many layers of each would you put down and how about cure times?

          would you sand back primer with 2000/2500 grade before paint or not?

            I wouldnt bother sanding back with super fine grit wet and dry, that is a bit too keen for wheels in my book! If you really wanted bodywork finish on your wheels then go ahead but I think the lacquer would self level enough to make them look good. You also don't really want primer to be too glossy as that is not as good a surface for top coat to stick to, polish your lacquer for super flatness rather than primer.

            As for how many coats, if you are spraying through a gun you get more paint out of the nozzle than an aerosol so I'd do no more than 2 coats from different angles to make sure you cover all sides of the wheel spokes, if using aerosol, I'd probably do 3 lacquer coats to make a deep gloss and enough silver coats to make sure all your primer is covered!

              Thanks

              1 coat of acid etch and grey primer is sufficient? Just trying to get an idea of how much to buy of each to do 4 16 inch Fuchs.

                1 each for etch and prime. Once the etch has covered the alloy, another coat won't etch any more. Focus on building up 2-3 coats of colour and lacquer.

                    800 is as fine as you should go between coats too , anything finer and it doesn't provide a key for the paint. 600 is probably sufficient....

                          Upol is quality stuff.... depending how good your surfaces are, you may benefit with 1 can of #5 high build primer...

                            I had a look and it doesn't work out any more expensive than Halfords stuff on trade so I'll go for that.

                            They're stripped off all the old paint and I'll sand them back with 600/800 grit. Want to finish polishing lips before painting.
