REFLECTOR: priming "how to"?

[Grigore Rosu]

Thank you Ron and Al, based on your answers I did some investigation on the
web.  I'm affraid I cannot buy the primer from our local shops here in the
small Urbana/Champaign (mid Illinois), so I'll have to order it online.
There appear to be some options outhere, just to confuse me :)

Option 1

*Awlgrip 545 Epoxy Primer White Base awlD8001GL*
*   mixed 1:1 with*
*Awlgrip Converter for 545 Epoxy Primer awlD3001GL*

and

Option 2

* Awlgrip 545 Epoxy Primer White Base awlD8002GL
   mixed 1:1 with
Awlgrip Converter for 545 Epoxy Primer awlD3002GL
*
The difference between the two is "001" versus "002".

In both cases, it is recommended to reduce the mixture up to 25% with

*Awlgrip Std. Spraying Reducer for Epoxy Primers awlT0006GL.*

I'm assuming we spray this primier.  Brushing it comes with a different
reducer.

Am I on the right track?  Is this what you are using, too?  Which one should
I order, the "001" or the "002"?
Also, these appear to be rather expensive ... Apparently they can all be
bought in either quarters or gallons.  Can you estimate like how much of
each I will need for my airplane (Velocity SEFG, fast built)?

Many thanks again,
Grigore
