I assume that many people here are chaps and that they and, more importantly, their wives will not see 55 again - and that therefore KY jelly will have entered their lives (yes, I said Lives). I struggle with the tubes because they're so inflexible that it's hard getting anything out (subtly) once they're less than about 2/3 full, but I've solved the problem. I bought some "Silicone Travel Refillable Squeeze Bottles" from feeBay and squeezed the remnants of the tubes into them. The "squeeze bottles" are much more flexible than the original tubes and very easy to use. I went for 60ml bottles but, with hindsight, the 38ml ones would be better. Clearly this won't be of interest to those DIY'ing ;-)
Now back to sanding the stain off the garage door surround (it's too hot and I needed to cool off so thought I'd offer this piece of advice)
