DIY putty for filling seams

[TimM63]

I use Perfect Plastic Putty for all my seam work. I've heard using black CA works well, too.

I use Perfect Plastic Putty as well. Has always worked well for me.

I use PPP as well. On the repair of my A-6E I used Zap-A-Gap on the, ever present gap between the wing to fuselage, and it worked great!
I think it is basically a thin super glue.

On larger gaps I'll use sprue goo and/or PPP.
