The scuffs on the top panel are pretty bad
so just a "paint stick" type of approach won't help. I'm going to be
looking at wax & grease remover, sanding, self-etching primer,
chipguard, and paint. What fun.
If it's a flat panel (or a panel with no curves < about 120 degrees) then a
suitable wire brush attachment on an angle grinder can work wonders (just be
careful as too choice of brush as too hard and you'll scuff the metal too much
for a 'simple' respray).
Personally I'm not a fan of solvents for this kind of thing as it's difficult
to be sure that all the residue's been removed afterwards (and hence that
something left behind won't magically attack the new paint from below).
Washing and drying can cause its own problems (surface rust, water deposits etc.)
So I took the panel into a metal paint shop in town
well known for their
expertise to see about getting the paint matched. They said that since
the top is textured, the peaks & valleys will look brighter/darker and
thus you can't put a piece like that on one of those optical scanners
and get a good color match.
I've always been told too that it's just not worth it on old panels as uneven
sun-fading will result in a match that isn't "original" and won't match
every
other panel anyway. Matching by eye's a better bet (although personally I find
it difficult, but doubtless it's a lot easier for the professionals who do
this kind of thing every day!)
Since I know absolutely NOTHING about paint/painting,
I wanted to toss
this out on the list to see if what this place is suggesting sounds
right, and if the prices seem reasonable.
Seems cheap to me, based on some of the quotes I've had before on this side of
the pond. I've been told before not to mess around with aerosols though and to
use a proper spray gun as the end result will be a lot nicer. I've zero
experience of using a proper gun though, and have no idea how easy it is or
how much it would be to rent / buy one along with suitable compressor...
Note that all of this advice has been from automotive paint specialists; we
don't seem to have such a thing as "public general-purpose paint
specialists"
around here. I'm willing to bet that it's just as sound for computer panels as
it is for cars, though.
