Yea but wrinkle still looks cool, it's just not as tough. Mostly 50's stuff.
Hammertone is easy to do also. It's available in spray or regular cans (which I
spray). The formula has been changed to meet newer standards but it looks good and
is easy to apply. I even matched the color on some 50's gumball machines I
restored a few years ago. They're on my web page.

We used to touch up that type of finish at work (way back in the 70's, yikes!). We
used a piece of sponge or foam rubber and dabbed it on. That can help blend it in
and minimize mismatch. Worked great. Toothpicks, etc work fine for smaller areas.
The trick is to match the color or it'll stand out like a sore thumb. The
glossiness can also affect the job. Buffing is hard to do because of the texture.
Maybe I'm getting too picky here but you get the idea. They do make splatter guns
and there are always the commercial coatings guys that can do it but that could be
expensive.
I'd say if you want it matched, take it down to the auto paint shop and have them
match the color. Ask if they can match the glossiness (??) and if they can't, buy
some additive and do it yourself. Probably easier to find something close and
spray the whole thing. The "crummy airbrush setup" might work but it'll take some
time. I find that learning the process and doing the job is the best part of the
whole thing.
