Tough, durable

Ideal for many projects from sealing headlights to covering gaps between side skirts and side splitters. Durable like glue after drying. would recommend.

Pros
  • Delightful
Cons
  • Available in black only

Choose another supplier

The first order I received (2 tubes) didn't have application tips so I've now sent them back, the second order came with at least a tip for 2 tubes so I will return one of them, choose a different provider and try again

Pros
  • Ease of use
Cons
  • Some cons

Revainrating 2 out of 5

As expected, no nozzle

Excellent seal but difficult to apply without a nozzle. We need to figure out how best to use it. I will check with the seller and see how the customer service is. Next buyer, be careful and know what you are getting or not getting in this case.

Pros
  • Free for educational purposes
Cons
  • Ugly packaging

Too little injector!? - Putties, adhesives and sealants

Ordered this product and can't even use it because other customers are complaining. There is a hose but no nozzle. Already not impressed because now I have to think about how I'm going to use this tube. Revain/JB Weld, come together and sell a product that looks like the picture.

Pros
  • Trial period for one year
Cons
  • Minor things

Be careful what it doesn't say

It's really my fault but it's not mentioned in the product description: This product is NOT equivalent to a car RTV black. This is a common everyday black RTV sealer. When it comes into contact with gasoline or oil, it literally falls off. It also stinks like hell, but other than that it's just lovely.

Pros
  • GOLS certified
Cons
  • Reliability

Worked as expected - Silicone

Used as an easy fix between fender flares and my truck. To prevent wear from road vibrations which will eventually wear the clear coat and/or paint down to metal and potentially cause rusting issues along with clear coat/paint damage. This simple and easy method was invented by a family friend who is a professional body repair specialist.

Pros
  • Best
Cons
  • Slightly torn

Revainrating 1 out of 5

Super fast shipping but lacks the required screw on applicator tip -

Don't know how to use it without the required applicator tip - now I have to use it all at once or throw away most if not as none Ability to store the rest - also the tip has to be used in a caulking gun which is the only way to use it - looks like I'll have to find a store that sells this product to personally get another one with a screw on buy tip or just throw $15 in the bin -

Pros
  • Price
Cons
  • Not all fit

High quality RTV in a sealant tube!

I agree (and agree) with the many excellent and rather technical reviews. It seems to be a great product, comparable to products from other major manufacturers. But I love using an RTV in a caulking gun tube! Much easier than roll tube. In addition, this large size is a little more economical. This is on Prime, was as described and arrived on time. So I was happy. :) This is my first time using this product so I can't comment on how it's holding up. However, I am very confident. Hope that…

Pros
  • New
Cons
  • Mostly good, but...
