Epoxy Questions

I need to learn how to use epoxy in the restoration of rib ends and split or damaged stems from tacks. Any recommended teaching sources on Youtube or other sources? Any recommended product for this purpose. Looking at the major companies (West Systems, etc.) it looks like there are a lot of product choices.
Thanks

 

I would suggest searching those topics on the general forum...there has been a lot of discussion about this including very specific recommendations for both. There are also quite a few pictures included in the related threads.
You will find that there are differing ideas related and no definitive "superior" method for each. As many repairs vary in complexity solutions are also quite variable and adapted to the particular need.
Search on West Systems GFlex and you'll start to narrow down some of the stem fixes.
