how you can tel polyester from epoxy fuselage?
...i start working on an old kit, and noticed that my epoxies dont make strong bond,and thats after sanding very hard.
could this because the fuse is made out of polyester resin?...is there a way to find out if its epoxy or polyester?
thanx in advance for any info [8D]
