[_835_]

i think the trouble is the 1mm ... hard to bend even plastic one !!!
i use 0.5 mm plastic sheet and it's really nice.

And Before starting the modification :
- always study what you need to do.
- make template in paper...
- when the template is correct..you juste have to cut the same in the plastic sheet, glue, add putty...wait... sand..sand..compare with what you want...sand... and finally prime to watch error... most of the time need to add putty and re-sand. ;-)

It s not the "universal" way..but mine..and it works well ..


But better modeler can help you more...
