If bubbles land on your lens element can/will it harm the coating ?

Lens coatings are tough. I seriously doubt bubbles are going to do anything to a lens coating. Not unless they're picric acid bubbles.

I agree. My 24-70G is so hit or miss on the flare.

But my 17-35 ED, and my 35 f/2 D flare just right.

And I struggle to find lenses that don't flare at all.

the bubble won't harm the coating ... but if you leave a bubble on and sit the lens in the sun on a hot day...it may become hard to clean.

Most coating are done under high heat with evaporative material, another process would be in a tank using electric discharge method.

Modern exterior lens coatings are really tough. You'd really have to try and damage them...either a drop right on the element or cleaning it with sandpaper or something. Interior coatings can be pretty soft though, and very easy to damage. Spit on it, wipe it with your t-shirt, and the bubble is gone.
Oh, and Doug--try a Dremmel tool with a felt polishing pad and a really mild abrasive (I've used cold cream believe it or not). That was with really old coatings though...you might need something more aggressive with the new stuff .

Pretty tough to do. the coating are probably a stack of different materials all measuring in the 100's of angstroms.
there are different combinations that give different optical performance in different areas of visible and non visible light.
