H'mm, that is not a bad idea.
Here is what I would "not" suggest, do not use any kind of silicone-based caulk. It's the wrong application for this flexing situation.
I "would" suggest this, Proflex RV in clear or bright white. The color choice is yours, pending what you can get.
Proflex RV is rated for vinyl and can deal with flexing and UV. I have used much of this on the camper siding joints with very good results. https://www.geocelusa.com/product/pr...xible-sealant/
I would try it using this method:
1. Clean the top awing exposed area from all dirt and/or mold with the cleaner you choose as needed. Rinse well and let it dry.
2. Wipe the stitch area plus about 3/4 to 1" on both sides of the top stitching to remove any cleaner residue with denatured alcohol or home isopropyl alcohol. Let it evaporate off.
3. Apply Proflex about 1/32" to 1/16" high (thick) smoothed-out bead over the main stitched area and about 1/4" or so beyond the stitches on both awning length-wise sides. Feather out the edges of the bead onto the main awning.
4. Let it cure overnight or longer before using the awning.
Tips on using Proflex if you have never used it before.
Do "not" apply in high heat, full sun hot vinyl, it cures too fast, and you cannot smooth it out; it globs all up. Wait for a dry, cool morning, evening, or cloudy day, ideally below 70-75F degrees.
Only apply about 2 to 3 ft of chalk at a time, then smooth out, then apply more. If you apply too long a bead, it will start the curing action and glob up and not smooth out.
Use a wet soapy finger to smooth it out. Do not wet the dry uncaulked area. Suggest 3 - 5 drops of Dawn dish soap in about 2 oz. of water to do the awning. You do not need much.
Where to buy it: You only need 1 tube.
The supply chain was really bad during Covid, with shortages all over. It is now coming back in supply at lower costs than the crazy $35 a tube during Covid. I used to buy it for about $7 a tube at RV Upgrades by the case before Covid.
Last week, at our local RV dealer, they had it for $11.30 a tube. Check your local dealers.
RV upgrades have it but charge freight unless you buy over $99 of other RV stuff, then free freight. https://www.rvupgradestore.com/shop-...rch=proflex+rv
Amazon has it, but the costs and shipping are all over the map. RV upgrades, even with freight, might be cheaper or your local RV dealer. Shop for it.
If you try this, let us know how it goes.
