The fuse panel are overlapping going to the rear, I put down two layers of masking tape behind the line, then I build up with 3M Acryl Glazing Puddy (auto parts store) then I sand the puddy down to the level of the tape. Pull off the tape and you have the impression of overlapping panel lines. The lines on the wing and tail--i put down 1/64 tape paint over it and then pull the tape up before final paint--it leaves a nice indention in the paint that looks very realistic.
Your plane is smaller that the 80 in I fly so adding all this weight may not be too good an idea.. i Dealing with larger planes the weight is not so critical
Hope this helps
