Rain Repellant

[spongee]

was following this thread kaso hindi nabanggit kung ano ang pinaka -ok na repellant na di makakaapekto both sa windshield and wiperblade..suggestion naman po...para na rin sa sidemirrors kasi hirap ako pag naka-bead na water dun. TY

pls comment on this...when i was young, saw my dad scrub cigarette whole or butts only during a heavy rain dahil biglang nagstall yung wipers ng oto namin..the effect i saw was nagglide lang yung raindrops at di nagbibeads...any comment po? TY again.
