An Excellent Product For Certain Applications
I needed at least four tubes to seal a very old project car. This type of sealer does take a considerable amount of time to completely set up, but not a concern in this instance. Has more flexibility and can more easily conform to rough/mismatched sheet metal than other RTV brands on the market. For my particular application, this was the right combination of economical cost and performance.

Very durable sealant...but not fast curing!
I bought this sealant to help seal the slide-out of my travel trailer. I used a caulk gun to apply the sealant to the trailer once I had prepped all the surfaces. The sealant goes on very easily. Although it can be a little sticky at times. I used soapy water and some kitchen roll for cases where I applied too much or got it on my hands. In the first 5-10 min it will easily come off if you make any mistakes in applying it. I have had it on my trailer for a few months, and I am really impressed on how it stands up in the weather. Our trailer sits out in the full sunshine for most of the time, and the sealant holds up very well. The only "negative" is that the curing time is about 24 hours not 30 minutes if you apply it in large quantities or in a large area like I did.

The black dye runs
I don’t recommend using this product unless you don’t really care about the surface you are putting it on. It will stain any surface you get it on, black. It applies well but once I sprayed soapy water on it to remove the excess and create a smooth joint the dye in the silicone started running down everywhere and it only got worst as I tried to smooth it out, creating a big black mess on my wall. Luckily it did eventually come out after a few hours of using a rag to buff it out.
