PRKAF50 Anti-Fog Defog System for Windshield - Defogger Spray - 1.7oz Pack

works well but doesn't last very long at all

when I was buying it, i read most of the comments were negative as it simply did not work as it supposed to be, however as it was not really an expensive item i bought it as an experiment,when I applied it for first time it didn't work, i sprayed as per instructions on my visor and wiped it with a tissue paper but it didn't work however there's another method written on instructions, that is to spray it on a tissue paper and apply it visor, just don't rub it wipe it once and you're done. look for areas that are not applied by breathing on your visor then apply this anti fog on those particular areas, don't expect it last more than 2-3 days.I'm super happy to have it, i just used it on my Delhi - Nainital - Delhi trip, it has done a wonderful job.

Applied on the tinting plastic foil I have on my windows. Seems to work, not like Rain-X anti-fog, but acceptable. Rain-X anti-fog is bad for tinting foil which is the reason I had to get it.Because is biodegradable if you apply it in subzero temperatures tends to freeze on surface when applied by spraying...NOT happy with this.

Totally waste of money never does the job. I tried many times after using it my windscreen looks like some oil is coated and visibility going bad never recomended for car. I will create accidents on night driving . I tried in many cars and diff qty same results. After using it it created lot of mist and water formation on inside glass totally waste of money and time wasted to remove this solution not easy.

Working good, but not lasting, better not to use cloth or microfiber cloth to apply this liquid, just spray then use sponge to spread all over the glass and wait until 5-10 mins and wipe with any cloth or sponge, working good but somewhat fog is present on the inside of the glass when using heat air, not sure how long it will last, I applied 3 times in 2weeks, and it's not as I expected.

Method to apply it -a. Spray on the glasses/visor. Leave it for couple of minutesb. Wipe it with soft hands with a clean (preferably a micro-fiber) clothEffect -a. The effect stays for few hours, when it is used at a stretchb. I observed the effect is reduced if the surface on which it is applied is exposed to cold weather (when the visor is opened for few minutes in between, or when we remove the helmet)c. The effect goes away completely if we try to wipe it again thenSide Effect-Poor visibility when using in the night. The light glares more when this is applied. But still the visibility is better, as compared when if there is a fog on the visorOverall -> Worth the money, it does the job
