ORIGINAL: mtnflyer14 Condor60, The finishing resin I used is made by Pacer Technology in California; brand name Z-Poxy. Comes in two 6 oz bottles, mix 1 part to 1 part, but you can also thin slightly with Rubbing alcohol. I didn't thin and it worked fine., can't remember which. Good luck! Regards, Mark

Thank you for contacting me back channel. Your Byron P-51 brings back memories... Looks like you are moving along, learning how to merge what was...with what is...today. If I may be permitted to recommend something specific I recommend you definately utilize
Pacer Z-Poxy Laminating Resin in the glassing process for your wing.
PacerZ-Poxy Laminating Resin is unique in that it has minimum parafin released during its cure resulting in superior interlink of any subsequent application with minimum prep.
Furthermore, I highly recommend you dilute the Z-Poxy resin "30%"
"after" you have mixed appropriate A~B components per the instructions on the Z-Poxy packaging. This accomplishes two things... (
1) it assures you achieve the proper linking process between component A and B of the laminating resin and (
2) when properly mixed the "30%" dilution of the A~B mix with
"90% DENATURED ALCOHOL" will reduce the viscosity of the properly linked A~B components to permit greatest wicking to occur when "rolled"
through the glass cloth during its application.
Pacer Z-Poxy is epoxy, not polyester resin. Polyester will dissolve most EPS foam...something that will ruin your day. Secondly, you should disregard any instructions in the Byron kit giving directions of how to mix their original epoxy resin...it was by mass rather than volume as is the case with the Pacer Z-Poxy...the
proportions of A~B are 50/50 with Z-Poxy... Otherwise will lead to a very bad day the next morning after you do anything else....don't ask!
The only other thing you need to know is apply the Z-Poxy with a 3" wide foam paint roller to best distribute the minimum amount of epoxy you apply from the center of the wing out in all directions and over the edges of the foam components
starting on the bottom side....let cure for 24 hours before trimming off excess perimeter cloth by lightly sanding perimeter with 320 grit wet/dry on a sanding block (dry)....then wipe down the glassed surface with a soft cloth soaked in denatured alcohol to loosen and remove any parafin and cloth reminants before turning it over and repeating the entire process on the opposite side.
