Panel colour change

[andeep]

Hi there,

I have a pair of used wings that I need to spray for my E30. They are red and I need to spray them black, so just need a colour change.

The wings themselves are perfect and don't need any work on them.

On previously paint jobs if I want to do a colour change, I sand the panel down with 400, high build, sand with 600, then basecoat and finally lacquer.

I have been told that it is not necessary to have to reprimer the panel if the paint is good and doesn't need any work.

How would I go about in spraying the panels? I was thinking of doing the following:
Grey scotchbrite with sanding paste
Basecoat
Lacquer

id go 800 wet or 400 dry sanding ...just so that any peel is removed

So 800 wet then shoot the basecoat and finally lacquer?

Is 600 too rough?

800 wet would be my choice

600 is a tad rough , possibly see some slight marks but would polish up ok

If the base coat is met, you may have to blend the doors in so get sufficient colour.

Thanks for that.

I also need to do the inside jambs of my doors, could I just scotch brite them with sanding paste? As this is around the equivalent of 800 grit?
