[Shotimes] painting?

[John Phillis]

Hi,

^ professional auto body technician with some advice.
Rust will not be defeated if you just cover it up with spray paint.  you 
must strip all areas with 35-40 grit on a high speed sander. 3M makes roloc 
disks in 2 inch diameter which will work best for what you are doing.  once 
you get the areas stripped down so that no rust pits or dark gray material 
is evident, you must treat the metal with self etching primer, epoxy primer, 
or a U-pol primer(such as PPG NCP-270)

if you use a self etching primer, you must then apply the epoxy primer 
overtop and then your build primer to get it back to shape (removing sanding 
and grinding scratches).  You can use a good epoxy primer in place of the 
self etching primer. Such primers as MAtrix MP-480 are lead based epoxy 
primers that will etch nicely. You have to mix the primer, and then let it 
sit in the cup for a 1/2 hour induction period. You can cover it with K-36 
PPG build primer, and then start wetsanding. it's easiest to start with 400 
grit, and then reguidecoat it, and go to 600 grit, and use a 3M red very 
fine scotchbrite pad for hard to reach corners and things.  then you must 
apply a sealer and then you can paint it. for sealing, you can use the 
MP-480, mixed 2:1:2  sealer:activator:DT reducer.  That is probably the 
easiest.

for final paint, the exact match for those parts is SEM Trim Black.  You can 
buy it by the quart or in spray cans.  it doesn't need to be reduced or 
activated.  it burns completely flat just like OEM.

Hope this helps.

John

Some of the flat black painted areas of my car are starting to rust or
show metal as the paint has 'worn' away.  Specifically, the mirrors and
the side panels between the windows on the doors.

Anyone have any ideas on how to repaint those and with what?
