Used Vivante mostly on clothing repairs - never had to return something to fix.
Then used Dubun for tip of boot new covers and add material for gear lever. They fitted non standard tips, protruding too far, and looks bling. I painted them black just to not feel embarrassed in public. The chrome bling is coming through due to scratches but it is better than the full tip being chrome.
The material added for gear lever protection is also coming loose.
I won't be using Dubun again although I wait longer for Vivante to complete fixes
