Put me down for the drawings asap!
Cheers,

low, root first couple of ribs are worst on one wing compared to the other,
both bottoms of my wings have ripples by spar. I am only going to make sure there
are no fast changes and perhaps go a little heavy with high build primer on
low areas. Plastic aeroplanes change shape, not worth it IMHO to make things
perfect at the expense of a lot of extra weight and time needed only to have
it change shape on you. I am striving for a nice 5 foot aerolpane, looks nice
from 5 foot but is an aeroplane that is usable and if a repair is made it will
not stick out too bad compared to trying to initiate a repair on "Symmetry".

hardener, wait for it to get good and tacky then apply Expancel very very dry
with 60 minute hardener. for smaller filling I use Aeropoxy light. BTW you can
go wet on wet with Aeropoxy light if you see you missed anything with Expancel.
Nice thing about Aeropoxy light is you don't need to wet out and get a water
line of hard epoxy to give you a hassle when sanding. For final mini filling,
even larger areas that are 1/32" thick I like 3M flow-able finishing putty,
it can be sanded in short time. Then will use PPG DPLF thin as an adhesion promoter
and use PPG K-36 as a high build primer, then for final finish seal with
DPLF and final coat use my color PPG DCC.
