I supervised the recover of both a Taylorcraft and a TriPacer with Stewarts 
system in the last few years.?? I have to say, the TriPacer came out 
exceptionally nice as the owner also put a lot of $$ and work into it besides 
just the cover.? But the Stewart system is simple and relatively easy to do if 
you follow their instructions.? I didn't care for the cost of the Stewart 
systems, but otherwise I thought it was a good covering system.?
?
I have also covered using the Nitrate/Butyrate, and Polyfiber systems.? All of 
them work well, although the Stewarts system is significantly less toxic to 
work with.
?
I have also done quite a bit of paint work as well, although I don't consider 
myself to be anywhere near a "professional" quality painter.? However, I have 
used a lot of different types of paints.? Stewarts would not be at the top of 
my list of paints that I would use on wood and/or glass.? However, I do 
understand using it because of the lower toxicity.? I'll write my evaluation of 
the various types of paints below based on the last 20 years of painting planes 
and cars, some of which came out really good, and some of which didn't.

All of these paints must be used with either a fresh air source into a hood, or 
a chemical and particulate respirator along with an adequate quantity of fresh 
air.  
?
Acrylic Enamel - The first professional paint I ever used.? I found it to be 
easy to spray as long as you were close to the recommended temperatures, but 
found that once cured, it chips quite easily and tends to be pretty brittle, so 
touch ups and repaints are in your future if you use it.  Also pretty toxic 
stuff.
?
PolyUrethane - Can be difficult to paint.  Loves to "Orange Peel" if anything 
is less than perfect for conditions.  But leaves a gorgeous finish in the event 
you get everything right.  Sticks to darned near anything.  Is also pretty 
flexible as I have shot this on top of dope and fabric and haven't seen any 
kind of significant cracking after 5 years of service.  Probably one of the 
most toxic paints you can use.  Also, many PolyUrethane paints are quite 
expensive >$300/gal.  (I found the overspray from PolyUrethane stuck to my next 
door neighbors $150K Cirrus very nicely, which was a lot of work for us to 
clean back to "new" condition).

Base Coat (urethane) / Clear Coat (PolyUrethane)- The Urethane Base coat is so 
easy it's like spraying primer.  You get spoiled by shooting the base coat.  
Then you spray the clear coat.  Well, it's clear, so takes really good lighting 
to be able to see how you're spraying.  Like the PolyUrethane above, it loves 
to "Orange Peel" and is really easy to get runs and sags since it's clear and 
you can't see it.  Also, since it is a PolyUrethane, it's pretty darned toxic.  
However, you can lightly sand and polish out the runs, sags and orange peel to 
make it look good.

Acrylic Urethane - My current favorite.  Sprays easy like Acrylic Enamel.  Even 
uses the same catalyst.  But is much more flexible when cured, and seems to be 
as tough and durable as PolyUrethane.  This paint seems to have the good 
qualities of spraying easy like Acrylic Enamel with the shine, durability, and 
flexibility of PolyUrethane.  But, it's still high on the toxicity scale.  This 
is what I recommend for amateur painters like myself as I get good results with 
a shiny durable finish without the need for a paint booth and superior lighting.

Stewarts Acrylic Urethane - You want to follow the directions to the letter 
including prep work.  No short cuts.  If you stay within their directions, it 
paints reasonably well and will give you a good finish.  It's used over fabric, 
so is clearly flexible and has reasonable durability.  Stewarts is the least 
toxic of all of these paints and there is a lot to be said for using water as 
your reducer and for clean up rather than chemicals that like to attack your 
liver when inhaled or exposed to your skin.

I have the Stewart Systems DVD instruction set. I plan on using it on my
Tri Pacer in a cpl of years. School of Missionary Aviation Training at Y70
uses it exclusively. I looked at several systems and I like Stewarts the
best.
Great Luck to You!!

and it seems to be holding up much better (rolled on).----------------

A reminder to everyone. Stewart Systems will be doing a forum Saturday
morning at the Gathering
