I drilled the platenut rivet holes on the right spar, countersinking, debured and primed same. I then riveted the fuel tank platenuts into both spars using a hand squeezer. The platenuts have some kind of coating which will come off onto the fingers. Note: don't wear white t-shirt when working on the plane, self evident really.
