From the page that your link brought me to.
"Mcnett Aquaseal Wetsuit Repair Adhesive Sealant
Urethane-based adhesives are the best for achieving maximum strength and durability".
Aquaseal is urethane based not silicone based. I wouldn't use this on your silnylon tent!
"SilNet™ Silicone Seam Sealer
Specially formulated for sealing seams on tents and other outdoor products constructed or coated with silicone, such as silicone treated nylon".
"...Aquaseal is part of a comprehensive line of Care and Repair products from Gear Aid. With Gear Aid, anyone can be a master of gear repair.
Works with neoprene, nylon, GORE-TEX® fabric, Nypalon®, urethane, rubber and other materials".
The above info is copied and pasted in part from McNett's website. Notice the reference to nylon, not silnylon for the Aquaseal.
Copy and paste the above link and scroll down about 2/3rds of the page and read step one of Silicone Tents / Silicone Treated Fabrics.
I cannot be sure but I would think that once the Aquaseal is completely dried and cured after applying it to the top of your trekking pole handles you should be able to set up your tent using the inside pole technique that you favor.YMMV
If it were up to me I wouldn't mix silnylon with the Aquaseal even after it was dried and cured. I'd go with something silicone based and play it safe with my expensive piece of gear.
In my opinion Silnet needs to be thinned. Silicone sealant needs to be thinned also. I have had good luck with the Permatex product and many others on this site also recommend it. Also it does not need to be thinned. I'd spend six more dollars and play it safe with my tent / tarp.
Good luck with whatever method you choose and enjoy your overnighter.
