scuffed back metallic

[Ed74mnd]

Hi,

(on test panel) I scuffed back my metallic red single stage paint in prep for clear coat.

This appears ot have changed the look of the metallic.

where it was once shiny red particles, there now appears to be much more silver particles.

Seems to be a result of sanding with 1200 grit paper (used wet)

Is this a result from perhaps sanding the tops off the metallic particles?

I'm not sure if i find it acceptable or not either...

any clues?

Cheers

ED your right, metallics and pearls should not be sanded directly. to make it right it must be rebased, next time either use intercoat clear or urethane clear for a protective barrier.

Cheers Joe,

The paint was actually not bc/cc, rather a single stage glossy metallic.

I'm wishing to clear it, will i get adhesion without scuffing it first?

failing this i will get the paint mixed up in bc/cc

No..you must scuff it first or the clear will lift right up.......use a red scotch brite pad and just lightly scratch the surface of the single stage.It will look like your messing it up but the clear will fill in all the scratches you made.
...........
But in order for it to look right you must fix your prior mistake by repainting the single stage because the clear will not cover up the imperfections you made by wet sanding.

Thanks Bejetts,

will try the red scotch brite no problems.

this is all on a test panel so mistakes are no problem, i want to get it right for the project.

Cheers

Actually, You should not scuff or sand any metallics. You will scratch the metallic platelets and screw up the job. To do this right you will have to repaint the base coat. Sorry. Your options for shooting clear are:
A. After your base coat flashes, shoot a couple coats of intercoat clear over it. Then you can let it all dry and sand or scuff it before you shoot your topcoat clears.
B. After your base coat flashes and dries to a tacky but not stringy stage, shoot the clear coats over it then.

For best results never sand or scuff a pearl or metallic.

Good luck.
