Hey Grrumpy!
You mentioned a cloudy look to the paint. Without seeing the
paint, I'm going to guess what you're probably seeing is micro
marring in the finish. While a glaze or non abrasive polish can help
clear things up, nothing beats a good polishing procedure to really
bring out the color and sharper reflection. There are quite a variety
of polishes that you can use that will help in that respect. Heres
some of the polishes I use that help clear up the finish for me:
Menzerna Intensive Polish
Hi Temp Light Cut Paint Leveler
Poorboys SSR 2.5
Poorboys SSR1
Menzerna Final Polish II (aka Micro Polish)
Optimum Polish
If you're working outside, I would go with the Poorboys or
Optimum. Both brands work very well when polishing outside,
but I have found that Optimum has a much longer work time,
and dose not dry out very quickly; even in comparison to
Poorboys. Another great thing about Optimum, is that you can
use this with basically any foam pad you have, so there's no
worry about x-contamination. You can do light paint correction,
light cutting, and polishing with this one product.
If you're working indoors or out of direct sunlight, the Menzernas
are the tops, IMO. I've found few polishes (save for maybe Optimum)
that can really bring out the gloss and finish like Menzerna's
Micro Polish or Nano polish (aka 85dr). They require a slightly
higher learning curve, but I have found very few folks that
have anythng bad to say about these products. One youve
done your polish work, you can still add a glaze if you like.
This will add even more depth to your paint.
As far as waxes and sealants go, there way too many good ones
to choose from. The only way to find what you like will be
to experiment.
