^^^This.

I found no advantage to waiting. Masking tape is very helpful.

Love the 4-40 nut idea. That's one for the bag of tricks. Larry when you went back a day later did you apply fresh pro seal to the rivets?

One more data point
 
For my trailing edges (RV-10 uses AEX wedges in the TEs), I let the Proseal set up, with clecos in every hole, then riveted, for less mess. For my fuel tanks, I let the first one set a little before riveting, but still pliable so the ProSeal squished out. The main benefit was I could have the clecos hold things in place while I did some cleanup, then when I riveted, the little bead that squished out could easily be filleted. Second tank, I just did wet, which was slightly messier, but not much. Both tanks passed their leak tests with flying colors, so take your pick with the method. I think the only way you could potentially get into trouble would be laying in too much proseal, not using adequate cleco force and letting the whole thing harden before riveting. This could provide more separation between parts that is desirable. My $0.02. Have fun and be sure to wipe your nose/face a few times during the process. Amazing how itches arise at the most inopportune times.. :D

First the nuts. Unfortunately, 4-40 is a tad too small so I drilled them #40. 6-32 was too big. It only took a few minutes.
Yes, I used a stick from a Q-tip to apply proseal to the hole before inserting a rivet. Also, several other steps that cut the mess to almost nothing.
It's all documented on my blog.
