Hi,





Removing the paint or not will depend on the state of it.


If it's in good condition the first thing to know is what kind of paint it is. Otherwise other stuff going on top may wrinkle it.


You'll also have to use a primer according to the paint you're going to use - again taking into account the paint already there. Mind that although one usually cannot use acrylic (solvent based) over synthetic, there are surfaces who permit an isolation of the synthetic to receive acrylics or cellulosics.


Anyway, sand the surface with a P600, for insteance, the degrease it. Apply the primer. The apply the paint .


It is important to respect the time between layers otherwise the solvent between layers won't evaporate (flash off) and you'll have problems. Either soon or later.





Now, if the paint is in bad condition, sand it down to the alluminium.


Your market is different from the market here in Portugal, so maybe you'll find a paint that can be used directly on alluminium (you may check Krilon/Krillon (?) )


Usually when painting on alluminium or zinc one uses a fosfatizing primer (2 components) or sometimes a Washprimer (2 components). These are applied with two VERY THIN coats. Then one can apply a regular primer.


Another primer that can be used on alluminium is an epoxy one (Ferrari's boddy is alluminium and uses an epoxy one if I'm not mistaken).


And that's all.


If you have any doubt, just e-mail me.





Take care,





Jos茅

ah just put a great big sticker over the lot of it
I'd use quick dry acrylic spray unless you have access to professional equipment and a spray booth, (I'll assume you havent otherwise you wouldn't be asking on here) most pros would use two pack but it gives off toxic fumes so dont go up that route. high build primer will help ( but costly ) unless the aluminium has some oxidisation, I'd just flat off (take the shine off the existing paint) prime and spray over the top. If it has then treat the localised areas with 40grit emery cloth then a lighter grade to finish off, high build prime and do the same for the rest.





Im assuming this is a commercial grade paint job not a show winning custom finish you are after.





Hope this helps
