How To Paint Onto Polished Metal?

[iz32]

gday,

Im planning to paint my oil catch can and angle brackets in a basic black gloss tomorrow....

could i get some tips on how to prep the surface cos it has a very shinny smooth finish and i dont know if they are made from a cheap chrome look coating or simply, polished metal.

heres some things i came up with:

1) do i use wetndry sandpaper to prepare the metal surface and just paint over it,

2) or do i take the whole entire layer off with a metal brush and corse paper to remove the polished area totally before painting?

>>> also should the surface be cleaned with toluene at some stage?

3) should i use a primer? or a specific "anti polished metal" primer before painting?

4) or do i just hit it with the paint & primer combo specials....?

all tips are most welcome

regards

Izad

you will need an etch primer on the metal surface, followed by a std primer then sand then paint

if its not metal but chrome stuff, sand that off then prime and paint

1. clean it.

2. best way to paint alloy is to use 400 grit wet and dry paper with hot soapy watar, (this is a must). keep sanding until all areas no longer have a shine. if you have a orbital sander 240 grit dry will be fine. as the primer will fill the scratches.

3. clean again

4. yes you need a primer. with alloy you should use a 2 pack primer but if thats out of your price range than a etch primer will do, or a std acrylic primer but don't use an orbital sander with 240 grit to prepare. now leave to dry. give a light guide coat.

5. once dry wet rub with 600 paper. avoid using your fingers and keep your hand flat on the surface. don't dig in. if you can still see scatches then give another coat of primer and repeat this step.

6. and clean again

7. now paint. persanally I'd be using 2 pack.

hope i helped.
