The way it works is very simple. You basically pour it on the lens, let it dry, and peel it off. It works 100%, leaves no residue or streaks, and has no risk of scratching or damaging the coatings.


Then again...I looked here as well, and found a very negative report of this method:

So make of it what you will.



Wow, never heard of that method before. Sounds promising.. I'm guessing the part about creating a 'dam' so the collodion doesn't seep into the lens, isn't that necessary on an L lens?
