Wiper Judder problem

[autochi]

Mga Sir tanong lang po. First time ko lang gumamit ng rain repellant. Nagtry po ko nung MicroMagic rain repellent ung tig 99 tapos color yellow. Nangyari po inapply ko po dun sa 2 nameng kotse. Ung isa sa luma nameng hilander tapos dun po sa isa sa bago nameng car. After some time, bigla na lng nag-judder ung wiper dun sa hilander. Bale ginawa ko po bumili ko ng bagong wiper para dun sa hilander tapos mukhang ok naman pero un ule may lumabas nanaman pag judder pero onti na lang. Kinatatakot ko baka mangyari na rin un dun sa bago namen. Any feedback with regards to MicroMagic rain repellent product? Saka po hinge po advice baka sa salamin na ung problem saka kung anong magandang gawin. Thanks po!

You need to remove all the residue of the water repellant from your windshield.

You can either DIY this (with a windshield cleaning compound) or go to a car detailer and have them do it for you.

I'm using rain clear gel rain repellant. no issues even with my old wiper blade.make your windshield is clean before you apply any repellant

Sir anong magandang brand po ng windshield cleaning compound?

[yebo]

that will happen if you applied rain repellant (any brand, pareho lang formulation ng mga yan) on a dirty windshield. make sure you clean the windshield first before applying. what i do is clean it first with a strong mix of Joy dishwashing detergent at least twice to remove wax, oils and road tar. most of the wax comes from those "wash and wax" car shampoos. after cleaning with Joy clean it again using glass cleaner. avoid using ammonia based cleaners as it might damage your car paint. then rinse with water, dry with paper towel. don't use your chamois for drying as it will have wax residues in it left when you used it to wipe dry your car. then you can apply the rain repellant.

If you're planning on getting the Rain Clear gel, Blade sells it in kits with Glass Scrub, which is a glass cleaner that can remove slight watermarking as well as oils, dirt and the remnants of your current rain repellant.

around how much sir?

Hmmm, can't recall exactly - around 400, 500 I think? It does include sufficient product to suffice for multiple applications of both Rain Clear and Glass Scrub, though.
