Ive seen alot of posts about people asking about connecting the L1 and or L7 bridges on the Durons. Asking about what do I look for in stores and part numbers ect.. Follow the link and see for yourself!
Seriously the L1 bridges are very small and are hard to see unless you have a magnify-glass. I used a magnify-glass off my dads workbench. You might beable to do it without a magnify-glass, but I dont see how.
First shake the bottle up real good. Then I used a fine plastic tooth pick and just dabbed a little each time till i connect the bridges. Dont freak out if you drop a blob in the middle of the bridges. Because I did! Just have a bottle of Alcohol ready just incase. It will take the defogger stuff off. But try and do it right away if possable. Its best just to take your time and use small amount and keep going back over the bridges, instead of risking adding to much and dropping it on the bridges.
