Don't know if an alcohol wash was needed, but since I am very generous with the lubricants, there could have been residual oil preventing the Sugru from adhering.
Step 2: Knead Together 2-3 Packs Of Sugru
We got by with 3 packs of 5g, but your milage could vary..
Step 3: Use Fingers To Form A Thin Layer
We made oblong Sugru pancakes and pressed them on to a thin layer. After the surface areas were mostly covered, we then used mild soapy water to make it easier to smooth the Sugru out further, while preventing it from sticking to our fingers.
Step 4: Finished
Then I just have to not touch the new grips for a day or two. A more comfortable ride- here I come! :)
