3M Resin
Hello, I had a crash with an EDF l-39 made by HET. I believe it is epoxy resin. However, I need to do lots of repair work so I went to walmart and got 3M Fiberglass resin and 3m Fiberglass. From my understanding this is polyester resin.
Does anyone know if this will work ok for the repairs? lots of rips to fix in the glass, very few holes. Just need to sew the seams back together!
Never used it before, I usually use zpoxy but its too darn expensive for what I am doing.

RE: 3M Resin
Fiberglass resin is polyester. Polyester is very poor at making repairs, regardless of the substrate. Delamination and failed bonds are likely. Epoxy should be your first choice for making repairs even if the existing part is made from polyester.
There are quite a few companies like West Systems and Adtech that will sell their laminating epoxies in quarts.

RE: 3M Resin
I have bob smith 30 minute and 20 minute epoxies, as well as Z-poxy. Are any of these suitable? I guesss I have used them all in the past but trying to find the best thing to use to repair structural fiberglass damage (rips).
I found tha thet epoxies I have never seem to be like the epoxy that is used to make the jet.

RE: 3M Resin
The best way to make the repair is with a laminating resin. This is different than a bonding resin like the Bob Smith stuff.
West Systems 105 is a laminating epoxy resin that is available at many marine shops. You can order Adtech 820 directly from the distributer - http://www.adtechplastics.com/pc-64-...ng-system.aspx
US Composites 635 laminating epoxy is available from - http://uscomposites.com/epoxy.html
Some premium epoxy resins would be MGS L285 and Proset.

Pro Set has been a favorite for many years but it is pricy....It is some of the least viscous epoxy you will find, a cinch for wetting glass, kevlar and carbon. Finshed parts are strong and stiff even with no post cure, although higher temp exposure helps the cure time. Three different hardeners available depending on the working time one wants. I tend to use the slow curing and heat the parts to accelerate cure.

RE: 3M Resin
The West Systems 105 system is just fine. There are oodles of structures in the RC world that were constructed from it. Is the fast hardener going to give enough working time?
