More Preparing the Left leading edge - 3 hours

I had decided to change the order of process with priming. Do you prime and then dimple, or dimple then prime? Well with the 2 part epoxy that I had originally started out with, priming then dimpling worked just fine. But now that I have switched to self etching primer is another story. Seems that dimpling after priming has a tenancy to scuff the primer exposing the metal in some areas.

So from now on with the self etching primer I will prime after dimpling and see how that goes. I wasted no time setting up. I scuffed up the areas that I want to prime, then I started dimpling.
 
Once I was done the dimpling I went back over everything with more maroon scotchbrite to ensure good adhesion. A round of degreaser and remover, a round of MEK, then a coat of primer.

Once that was done, now came the tedious task of deburring the nose ribs. I found that it is a bit tricky to deburr some of the holes as some burrs are stubborn to get out, and access to the inside holes is not easy. A dremmel tool with the scotchbrite wheel is your friend in this case. I also filed and smoothed out the nose ribs really well. Lots of work, but worth it. I finished the rib prep by dimpling.
