Barkeeper Pro

I was finally able to test this product in real-life puncture conditions... a 5mm gash caused by a piece of glass.
The product was effective, it allowed me to get home :) ! The tire lost just about 2 bars of pressure before the product sealed the gash, with 4 bars remaining, I was able to continue my journey.
I just have one major criticism: why add fluorescent green dye to the product ? :(
The latex Barkeeper still sprayed thoroughly the rear before sealing. ( see pic )
This green dye is very difficult to get back on clothes and the bike; my jersey is permanently stained, and I'm glad I don't have a white bike... The same product without dye would be better !
Oh yeah, OK, the color is a fun selling point... <:\ In practice, though, I don't like it !

I've been using Barkeeper since day 1 and I was curious to see what was the difference in the pro version. Not sure what it is, maybe the colour, maybe not, but I swapped to Barkeeper Pro.

When you believe in a product there is no need to try something else in the market. Definitely a pro keeper :)

Barkeeper pro al enkele maanden aan het testen.
De sealant heeft elk gat in sneltempo gedicht en ik heb geen banden meer moeten pluggen of vervangen.
+ geen drukverlies gedurende de dagen nadien. 1 x oppompen en de band bleef op de gewenste druk staan voor 2 weken (niet langer dan 2w getest)

Does what you want it to do, seal a puncture asap so you don't loose a lot of pressure. Surprised how big holes got sealed without the need of plugging them.
Additional benefit: Sealant doesn't get thick&sticky why the used tire doesn't get a dirty layer inside. So if you need to change tires to suit different circumstances, it's easy to rinse the used tires, hang them drying and you can you use the clean tires later again.

Nie wieder Probleme!
