Filling and smoothing seems the REAL easy way.
Is it just me,
I have not heard much talk about using alcohol to smooth an aircraft wing root after applying putty.
If this technique is used then no tedious sanding is needed.
I have tried this and it works great.
Just dab a rag in alcohol and wipe off the excess putty.
But, am I missing something?
It doesn't seem to be a popular method amongst modelers.
