Cheap and easy finish

I'm refinishing my Burny, that was the subject of the catalysed poly
thread. It will involve cutting back and overspraying the current
finish. I can't get nitro, and I want if possible to keep it cheap and
simple, using spray cans.

Has anyone used or has any ideas on car bodywork touch up cans? They are
an acrylic that seems to be self catalysing in the same way as poly, but
might have some burn-in capability that poly doesn't. The instructions
on the ones I looked at recommend applying light coat every 10 minutes,
curing for 24 hours, then buffing.

Any opinions would be welcome.

You hint that your choice of available finishes is limited by
legislation. It seems possible to me, therefore, that the formulation
of finishes you are allowed to buy might not be the same as for what
pass for the same products in other countries. You probably need to
get your advice from a fellow Australian and if not, follow the
age-old practice of trying it out first on something that doesn't
matter. As for testing compatibility with the existing finish, could
you mask off and spray a test sample into the control cavity or
something?

Good suggestions, thanks. I was thinking of treating the whole thing in
the spirit of an experiment. - If it doesn't work there won't be
anything lost that can't be recovered except the cost of a can of paint.
I was also thinking of asking for a quote from an acquaintance of mine
who does nice two-pack spraying of guitars. It is only the body, so he
might do it for a fairly low price - mate's rates with a bit of luck.

Spray can finish works fine (at least the stuff here in the US). It is a little difficult to spray as the width of the spray is pretty narrow. So it is tricky to get overlapping patterns that are wet on the edges (for best appearance). Surface prep is vital. It will telegraph any defects.

Do a number of coats of minimal thickness (just enough to be wet), rather than try to build a lot in a hurry. Let runs dry thoroughly and sand out before next coat.

Have fun.

Thanks Dave. I've just tried the first effort, using Rust Guard satin
black. This is described as an epoxy enamel, and it seems to dry good
and hard, albeit slowly. I found by trial and error that surface prep is
important, as are several thin coats. It looks OK now, because satin
finishes hide a multitude of sins, but I'm not sure it will age well. If
it doesn't, I'll give the self-catalysing acrylic a go. - At least it
will now have a decent undercoat.

I got your email OK.
