Zero.. My product came hard as a rock. Tried to get anything out with a chalking gun and got a tiny 1 inch line that was thick and barely spreadable. Couldn’t get any more through the tip.. Tossed in the garbage.

Sometimes hot glue just doesn't cut it. My favourite cooler bag has a blowout around the zipper that just wouldn't close up through ordinary means. I decided to give this stuff a try.It was a little tricky getting it open, so I used an aluminum decoration screw to open up the tube. The advantage is that it can also be used to seal the extension tube afterward as well. Fits a standard size caulking gun without a problem too. I do read labels on new products and found almost everything I needed to know there. The only exception is cleanup recommendations. Although I wore latex gloves while working with it, I still managed to get some on my wrist and fingers. Turns out that ordinary hand soap and a cuticle brush got everything off.As supplied, the applicator extension comes with a very narrow aperture. That worked for me, but it can also be trimmed for larger diameters. I used half a wooden coffee stirrer to smooth out the caulk. Worked so well (see photo) that I decided to try it on one of my winter boots too. There's a puncture on the left and the toe seal no longer adheres to the upper. Check out the post repair photos.It's currently Winter as I write this, so indoor curing temperatures are about 68 degrees instead of the recommended 75. At that temperature, the repairs were still tacky to the touch more than 5 hours after application. I waited until 24 hours later to test the repairs. So far, the repairs are holding well and are thoroughly waterproof. I'll repost details here if that changes. Highly recommended.

I used this to seal against the brick of my front door. The original Caulk had all dried up and was cracking heavily. I was able to scrape it away and apply this without issue. It looks nice fresh and clean. The caulk applied like any other silicone based caulking, it was easy to manage and was not too thick, so easy to smooth into a finish product.

I was hoping this tube of caulking would fit into one of my caulking guns. Turns out, I was okay. The tube is 8 7/16" long not counting the tip where the caulk comes out. The diameter of the tube is 1 7/8". The stamped date on the side of the tube reads 2024/10-2025/10 so it appears this product has a shelf life of 12 months. I got this caulking mainly to be used as a sealant and then secure some loose stone pavers. The sealant job went well in the basement but I'll wait until the snow is gone before I secure the pavers in the flower garden. I'm hoping I closed off the tube well enough as the label does say to use a soon as possible and refers to 3 days.

The usual caulk on my trailer, for whatever reason, has cracked and dried out. The manufacturer could used better material, but I suppose that would be too expensive. I like using silicone. It flows and shapes easily, and it lasts a long time after it's put into place. This is going to replace some old original caulking that failed and let in water around the slide.

This caulk is a little pricy. Easy to apply. The actual test will be how long it lasts. Time will tell

I have some bronze aluminum frame windows and panels on a greenhouse in need of resealing. I used clear before but it just looked hokey. I removed the bad weathered caulk and used this WELLUCK Black Silicone Caulk. Went on smoothly and actually made an older greenhouse look new again. After a couple of days I set the sprinkler to it and no leaks. The tube covered a lot of territory but needed an additional tube. I personally think its a good value for a good product.

I purchased this product to seal a new vent cover on my rv. The sealant is easy to use, spreads well, forms a good seal and the container held enough sealant to cover over other small areas on the rv's roof that needed refreshing.
