Finally ready to begin assembly of the R. fuel tank. Mixed my first batch of pro-seal by weight using my new digital scale. And yes.. The Pro-seal is every bit as nasty and sticky to work with as everybody says. I masked off all around the area where the stiffeners mount Cleaned everything twice with MEK and spread the sealer on both surfaces. Fully Cleco'd the parts together and made a nice "bead" of sealer all arounf the perimeter of each stiffener. After about an hour, i removed the masking and everything looks good. I'll shoot the rivets tomorrow and install the fuel cap and drain.
