“been going strong for over 4 years now with no leaks.”➕
“Never had a leak.”➕

Effective for sealing over old sealant

“No problems for two years now.”➕

Effective for sealing over Eternabond tape

“I like to over-engineer things.”➕
“it's held up just fine for at least 4 years with no sign of deteriorating any time soon.”➕
Effective for sealing roof skylights

Buyer’s Cheat Sheet

What to check before you click ‘Add to Cart.’
Patching can be done in winter with proper preparation.
“With a clean dry area you could patch it correctly.”➕
“Supacaz has the most color and pattern selection to match your bike. Their end caps also have design”➕
Legal arbitration notice included with purchase
“The weirdest thing about this product is that, inside the box there is a note explaining that you've entered into an arbitration agreement simply by purchasing the tape.”➕
Comparison of different sealant brands
“I also used Dicor butyl tape from amazon, which was way easier to use than the tape I got from VT.”➕
“Just make sure to prep the surfaces well, thats the key!”➕
Discussion on sealing methods for roof vents

Cautionary Callouts

Know the pitfalls before they catch you off guard.
ZIP tape may be a better alternative for temporary patches.
“They can get ZIP tape at Lowe’s or Home Depot and as long as it’s clean and dry, it would hold them over for a couple of months even or until they can get a proper EPDM patch on it.”➕
“if you do want a temporary fix, I'd use Zip Tape over something like butyl tape.”➕
“It is perfect: easier to install than Lizard Skins, lasts a long time, feels good in all weather, and costs a fraction of the price of the fancy tapes.”➕
