Quick building question

[Gray E Fowler]

Steve- Rubbing alcohol is a mixture of isopropyl and and water. Water bad. 
Epoxy hate water.......Plus amines (the epoxy hardener) really do not 
dissolve well in isopropyl. You are better off with methanol or denatured 
alcohol which is ethanol with a nasty taste killer so you won't drink 
untaxed alcohol.I do not know what epoxy you are using, but that center 
reinforcement is easy without cutting the viscosity. Bring it to my house 
I have lots of low viscosity resins.

Guys,
 
I'm doing the fiberglass reinforcement over the balsa sheeting where the 
main wings are joined on a .60 size kit.  Can I use rubbing alcohol to cut 
the epoxy with to thin it just a bit?  Do you think that would cause me 
any problems?  It sure would make it easier.
 
Thanks,
Steve
