bedding the stringers

[Curapa]

If you have it all the way down that far I would just start fresh. Grind off all of the old stuff and put down the new. It will probably be easier anyways.

Either way you don't want to use 5200 for a structural part. You may be thinking that the glass wrapped over the stringer will be enough but don't give it that much credit. 5200 has many great properties but shear strength is not one of them. You are gonna have to get familiar with epoxy glue, fillets and fairing anyways. Bite the bullet and get some epoxy supplies.
