Good day,

I am intending to use fibreglass as the covering material for the aircraft I am currently constructing. However, what to use with the fibreglass is becoming a problem. I know I require the actual 'fine-thread' fibreglass sheet, but the resin and hardener side is giving rise to confusion. I have come across two particular types of resin; standard resin and 'epoxy' resin.

In brief, the question is, do I still need hardener if I use an 'epoxy' resin? Epoxy is an adhesive, thus this raises the question as to whether hardener is required or not. Can the resin just be brushed onto the fibreglass sheet without mixing it with the troublesome hardener?
