Ratings & Reviews
I was really impressed with the service. The replacement lights were reasonably priced and exactly as described.The new LED lights exactly matched the existing holes with no modification. The tracking system was excellent. I plan to order replacement LED 's for all my remaining running lights.
This silicone sealant did a great job! With some restraint was able to use 1 tube for installation of 2 Ventadome Roof Vents, 2 Camco RV Plumbing Vents and 2 running light fixtures, all victims of the massive 5/8/17 hail storm in Denver. I had enough left over to touch-up the roof caulking. This sealant cures a bit slowly and gave me plenty of time to complete the installations. Some caulks set-up quickly and don't give you much working time.
I have a 16x7 v nose trailer I installed this in. I insulated the roof with foam sheets cut to size but the walls and floor are not insulated. I had to brace the roof of the trailer in order to support the weight of the unit. Overall it’s better than nothing and lowers the temp 10-15* below ambient which makes it bearable inside of the trailer. My 2000w generator was not able to power it so I bought one of the predator 3500w generators and it does great. It will last around 7 hours on a tank of fuel.
Kyle sent just enough to do my vent. I appreciate his help with information on what I would need and how to use it.
Easy to use RTV type sealant. I used this to seal around replacement vents in the roof of my Airstream. My only complaint is that it is not self leveling. otherwise it's a good sealant that should last for years.
Great product, arrived timely
All was a great and easy process. Thanks
Exactly whatI ordered, exactly when they said it would arrive.
Shipped on time and as ordered, easy to find the right part on site. thanks
Used it on sealing a battery connector. Worked great
I will give all of my products a 5 star review. I was very happy to find the box at my door. I have not been able to use any of it yet due to weather. I am excited to use it as soon as the weather clears.
Works as described great sealant
Product is excellent. Wish etrailer would stock this so it would be a closer to the cost of the same product in white. The white is nearly half the price of the black. That doesnt seem right on so many levels.
Like all silicone caulk, gooey & messy. Hopefully acetone cleans up the dried mess.

A bit pricey. A small squeeze tube of black silicone caulk would, in my opinion, have worked the same with less cost and a lot less left-over.
Fast delivery.
I ordered two bottles of the Tempro 644 and I was only sent one and the other one was an offbrand worth about x.xx. No refund or discount given - only option presented was to send it back if I did not like it. Very disappointed with etrailer
I use the sealant for a while when we rehabbed our 1970 airstream. It sealed all the old leaks that it had. That was six years ago, now it developed a leak where there never was one so this will stop it when I fine that #@&% leak
