can i please get your opinions on my test. i thought i saw a line after 5 mins so took casing off to get better look and there was definately something there but couldnt tell what colour. as it started to dry looked more and more like an evap. what do you all think. pics are a bit fuzzy as taken with camera phone so didnt pick the line up that well but hopefully you can see it. 1st pic was taken after 7 mins,2nd and 3rd at 8 mins and 4th at around 15-20 mins.
