I am seeing where my Boyce Aerospace V-2 fins on my Maxi Brute V-2 need some fillets to fill in the gap a bit.
I have AeroPoxy Light and White Squadron Putty now. Are either of these the best solution or is there better option?
If it were me I would use Hysol 9462. 2 part epoxy, 24 hr cure time. I think it is very good. Have used it for years. Will not drip or run. I would put it in a syringe and lay a bead in the joint, then run my finger along bead to fill and feather it out. It is white in color, so painting is easy.
Like David Schwantz I am a fan of Hysol 9462. Put tape on fin and body tube. Run bead of glue using long mixing tube (better mixing than short ones). Smooth with cake fondant tool. Remove tape right away.
