Not my favourite part of the build but it has to be done. The prep is slightly more onerous for the elevators as allowance has to be made for where the foam ribs are stuck to the skins and the spars along with the tape for the trailing edges. I thought I had masked everything that shouldn’t be primed but missed where the foam ribs glue into the front spar. No harm done but a fiddly job with a Scotchbrite pad to remove the primer. What it did demonstrate was how well the EkoPrime adheres to the etched metal.
Lots of parts and if took and day and a half to prep and prime all the components. I labelled each part again so that it would show through the primer.
