Re: A new (to me) clear coat

Not that I doubt you, but I was just told on a Yahoo modeling group
that I belong to that ~Testors~ was bad for yellowing problems and
that Krylon was the way to go.
The Testors Flat did nasty things to the Metalizer, like making it
more opaque; i.e. turning Burnished Aluminum into a metallic grey
(picture the finish on a Toyota RAV-4 - like that).
Krylon caused the test paint to pucker like my son did when he ate a
lemon.
And why the heck can't I find rattlecans of Metalizer Sealer? This is
what started this whole thing. I've even come down to getting a bottle
of sealer, cutting it with thinner and I'm going to run tests with
that today. I have the sealer-thinner cut at 50-50 - is that enough?
Maybe I'll save the Minwax for anything darker and if the sealer
works, save that for the Metalizers.

FYI, I have some bad experience with Minwax polyurethane clear
lacquers.  They seem to yellow badly in just couple of years.  Testors
Dull and Gloss cotes do not yellow.

I sprayed several pieces of scrap plastic with Metalizer Buffing
Aluminum, then coated each with a different sealer; Metalizer Sealer
(which is getting hard to find for some reason), Minwax, Testors Clear
Flat Lacquer and Krylon Clear (Krystol-Klear?)
The Minwax came in very close to the Sealer, the Flat Lacquer made the
finish seem like metalic grey and the less said about the Krylon, the
better. I brought them into the house (where it's MUCH warmer) and
will check again tomorrow morning.

I've generally found that these are *thicker* than the Testors. However
I've not tried them in a long time, so they might have changed them.

I ~think~ that I scored big time today! I had to got to the
hardware store, so while I was there, I asked the clerk if he had any
clear spray lacquer in stock.
    He did in the form of Minwax; Gloss, Semi-Gloss and Satin.
    Let's see:
         Testors = $5.29 for  3.00 oz = $1.76 per ounce
         Minwax  = $7.25 for 12.25 oz = $0.59 per ounce
    Yep, I think we have a winner!
    And the test shots that I ran today indicate the quality is every
bit as good as the Testors.
