Perfect for solar install on roof of RV
Review Image by Chief of Stuff
(Duplicate review to the one for the Tape rimer 94) I contacted 3M and asked which VHB tape to use for installing solar panels (aluminum brackets) to the roof of an RV (fiberglass). They recommended this one (VHB 4950) along with 3M Tape Primer 94. The primer is a lot more expensive than the tape but since I didn't want my panels flying off at 60 mph, it was a worthwhile expense. Simple to install (clean with alcohol, apply primer, apply tape, apply force while it cures) and it sticks with a vengeance. It definitely doesn't allow for do-overs so make sure you get it right the first time. The 1" is the correct width to use with standard z-brackets for a solar install. As a final extra measure, I applied Eternabond tape on top of the bracket to prevent water, ice, dust and dirt from working their way under and as extra support. I can honestly say that the roof of the RV will probably come off before the panels do. ... show more

Legit Tape
This tape is legit. As noted clean the surface. I mounted a couple of things at work just to see how they hold. Incredibly strong.

Great tape preparation is critical
I use this tape to attatch solar panels to the roof of my RV. I have three panels with over 50000 miles on them. I am adding another panel and did not hesitate to use this 3M tape. Highly recommend.

Great tape, super strong bond
If you want it to stay, this is your tape.. it's not easy to remove, as it's intended to be permanent. If you attach something with this stuff to paint or drywall, expect it to take chunks of the wall with it when you remove it. If you want something removable, this is the wrong stuff. Great, super strong tape. VHB stands for Very High Bond, it is legally a fastener and not an adhesive. Would gladly buy again if I need it. ... show more

Works if you follow the instructions
I use this mainly to replace the original foam tape used on the magnetic switches of my security sensors. The original tape tends to fall from the glass windows, especially when the weather is freezing. Having worked at 3M at one point in time, I'm familiar in the use of this tape. After peeling the protective layer off and applying to the device, you must apply a firm pressure to the piece for at least 30 seconds. ... show more

This Stuff is No Joke
Review Image by Rob O'Hara
I purchased this to stick a solar panel to the roof of my camper van. I was not convinced that it would hold, so I also purchased a permanent tape to place over the edges of the panel. The tape was unnecessary; this VHB tape stick quickly and as far as I can tell, permanently. Make sure you get things lined up because once it sticks, it's stuck! I've put 3,000 miles on my van since putting the panel on the roof and it hasn't budged an inch. ... show more

A great item for the toolkit
Ultra strong double stick. You may not think you need, or buy it for a single project, but you’ll be surprised how often you’ll be reaching for the stuff. I’ve used it, and its cousin (the thinner, gooier brown tape, which feels even stronger) to assemble projects with coroplast, repair food containers, make small signs with P-touch labels and clear acrylic stock, repair appliance facials and more. Need to attach chrome plated car logos? This will do it. Stick-on Velcro peeling off a hot surface? Back it with this stuff. I swear, it’ll make you eager to do some repairs! ... show more

A single application has held solar panels on my van for 9 years
I was skeptical when I first heard this adhesive tape was heavy duty enough to hold rooftop solar panels on my van under wind load at highway speed, but 9 years later they are still in place.
