How to reduce the size of dumped exe

As a test, I use Armadillo to protect a exe(24K), then unpack it,
dump the exe, but this one is bigger than the original(348K).
there are several sections:
1000 .data
20000 .data1
1000 .mackt
20000 .pdata
1000 .rdata
2000 .rsrc
1000 .text
10000 .text1
and I think maybe the .data1 & .pdata section could be removed.
I tried PE explorer, PETools to remove the section, but always get corrupted EXE. Is there any good tools?
or other method to reduce the file size?
thanks
