I like Invisible Glass Clean&Repel on glass and Lexan but some other people here have said it didn't work for them. I must point out that, in the case of headlight lenses, I apply Invisible Glass on top of acrylic sealant.
Plexus cleans and protects them from clouding over.
Most glass sealants are cationic and only bond well to glass not plastic. A paint sealant will be just about ideal for plastic lenses.
It seems to me that the headlight lenses stay cleaner longer with the hydrophobic coating. I'll test it by applying the product to only half of the lens and wait a week for a direct comparison.
It will stay cleaner for sure, but it doesn't help with fog or frost.
Never had a problem with fog on headlight lenses. One squirt with the headlight washers and any condensation comes off. We get frost maybe for a few hours on 3 days every year. Didn't see any frost on my headlight lenses when driving around in the Sierras last winter when there was light snowfall. No frost on the headlights in the morning either. The ragtop was frozen stiff.
They still have non-heated mirrors?
We spit in our diving masks and rinse with water because the lenses won't fog up for a while. Saliva is an effective surfactant. Anti-fog products are nothing but surfactants. Please, do not draw any unfortunate and ill-conceived conclusion.
“original” ? Is the current formula still effective ?
