Worked great!
This worked great on my ceramic birdbath that decided to crack this year after ten years of use. No leaks now. Crack was from one side to center and completely around that center piece. Now it works like new!

Food Safe ?
No where on the product is there any indication that this silicone is food safe. I am using the silicone to reseal a hydroponic grow system. I would love to have this product in a syringe. It was very messy to use the application tip that was included. Time will tell if there will be any leakage in my hydroponic system.

Initially thought I received expired product, but I was dead wrong.
In early June I purchased these 2 tubes of the RTV 4500 'food contact' silicone sealant and received the tubes fairly quickly, but they showed a stamped date on the tubes of 01/23, meaning Jan 2023. The stamping didn't say "expires on', nor did it say "manufactured on", so I assumed expired even tho the seller included a sticker saying the date on the tubes is the manufactured date, NOT an expiration date. To verify this, I emailed Silco Inc, the manufacturer, and they did indeed reply that the stamping on the tubes was in fact the manufactured date, and not an expiration date. Therefore the tubes I received were fresh, and not expired. I used only about 10% of one of the tubes, so far, and it worked out fine for my initial small sealant repair.

Effective but VERY offensive and toxic odor
Product is foodsafe and effective as a sealant and adhesive just as described. Cures clear. The package has serious warnings related to application within very ventilated space due to toxic fumes prior to curing - HEED these warnings.. I used a simple vented construction mask (over nose and mouth from home depot) and the fumes were manageable except for a few times they burned my eyes and managed to enter the mask. Fumes during install were all manageable but the Smell afterwards is VERY strong and offensive... I used this to adhere some felt to the bottom of some spare quartzite stone peices to make some cheese board gifts but they have to sit out for months before the smell isn't immediately present and it's still present if you smell the stone.
