I posted before but have additional questions:

1) There is a tear that extends over one rib on the wing of my dad's Sultan. It is silk & dope. Should I patch from rib to rib and glue the silk to the existing rib?
I understand that smaller holes will be done as a surface repair.
2) Can I use current coverings to do the patching? If so how much would the color differ. Right now it is a Navy Blue base color with white trim.
3) With the patching, etc. will this cause undue drag in flight, or excess trimming?

Thanks,
