Solid rivet question
This applies to our trailers but is not exactly to do with...
I bought a 2nd hand truck box, WeatherGuard aluminum. The PO drilled a few mounting holes for this and that. I want to fill those holes and re-seal it.
I have some aluminum rod and planned on drilling out the holes for a tight fit to the rod, cut it to length with a little to spare and hammering it with a bucking plate.
Do I have to counter sink each side of the rivet hole to get it to seal and stay? I'm thinking I might as that was how I've read the A&P guys do it.
Thanks for any comments.
