Hi Dale -

It would be very unlikely for you to have a bleed thru problem like you
describe if you used shellac as your barrier coat.  It is an amazingly
reliable coating, sticks to anything, isolates contaminants, and provides
a film that virtually any top coat will have good adhesion to, esp, if
you use the dewaxed version.

FWIW

Is the primer you use before spraying the laquer an enamel or just
something compatible with laquer? Is your final result prone to
chipping?, or does it stay a bit on the softer side and set up harder
over time. (which I like) Just curious as I am experimenting with some
different techniques including sandblasting to remove rust and animal
urine then building back up with automotive productsof various kinds.Yes
it's a pain but I've had some preexsistent stains return to discolor
spots in my final topcoats over time.

"Using shellac for the first coat should  prevent the fish eye."

I don't use shellac, but I hear/read so much about it, I have no doubt it
is an excellent way to go. What I do use for my plates though, is grey
(any color is fine I'm sure) metal primer that I buy at the auto-parts
store. I just use it to hit areas that I have sanded through to the bare
metal. Sand lightly after dry. Then I finish with spray can gold laquer.
I like to just keep it simple. As long as I am using the spray can laquer
for the finish, I find it very easy to use the spray can primer. I have
had excellent results.

Hi Diane,
               Varsol must be a Canadian type thing, for some thing you
guy's call some thing else.  Two great Nations separated by a common
language.  ( Churchill I think.)


None of the paint stores I went to know what Varsol is......

I bought a good quality gold enamel and one of those fill-it-yourself
spray bottles.  It looks much better except for the fish-eyes

Using shellac for the first coat should  prevent the fish eye.  The
oxidization is probably attacking the finish from below.  Just a
calculated guess. Some of the more expert finishers could probably give
advice in this area.
I have done one plate in this manner. The grey market Yamaha just 2yrs
ago.  The finish seems to be holding up OK. But more time will tell. 
Weather it will eventually eat it's way through again, I do not know. 
But I do know shellac can be a very effective sealer.  Leave for several
days to harden, before applying the finsh coat.
Hope this may help.
Regards Roger
