Glass Science question

[Chikselog]

1/2 - yup, elevo watermark remover does good at this. another thing to use here is mother's chrome polish or d' best polish. i purchased mine in handyman. use wet pranela or mf while rubbing the glass - remember keep the glass wet. btw, do a good wash of the glass first before using these. use glass scrub to rinse off the polish. i use meg's foam applicator for rinsing. judging from your description, matagal na kuskusan to from experience hindi ganun ka effective ang glass scrub kapag nanuyo na ang watermarks. for really stubborn water marks, you can use a new razor blade.
3 - prior to rain clear gel, make sure the glass is well preped and super clean. apply it immediately after thourougly drying the glass surface. a small amount of gel goes a long way. the small satchet of it is enought to accomodate all glasses of 2 4-door cars double coated + side mirrors to ha. i just used a soft paper towel for application.
4/5 - in my case, i just had it for a month and it still works well. that includes at least 2x a week of car wash. i haven't used my wipers ever since i had rain clear gel. since i got the time naman, i re-apply it after a month since tagulan naman. i just use glass scrub to clean prior to reapplication. it won't remove rain clear that easily. mahirap pwersahin ang rain clear gel matanggal.

thanks sir spyghost
hmm, yung regarding po sa #1 di po sya yung todo todong watermark na talagang kita, kita lang po siya pag umuulan tas wina-wiper.. i personally call it invisible water mark, di sya kita pag tuyo, di rin po siya bilog bilog, wala syang shape hehe..para bang naulanan yung buong windshield then natuyo agad ng araw, so parang may part, minsan buong windshield, may invisible water mark na nakikita lang tuwing wet na wet na ang windshield (pag umuulan) tapos tuloy tuloy wiper..

sayang talaga naubos na elevo ko, sa concorde sm north ko pa nabili yun, bihira lang kami pumunta dun eh
tsaka what if sir wala po ako nung mother's chrome polish? pwede pong after wash ko, rinse, then glass scrub agad? tapos dry, then rain clear? tama po ba?
TIA sir Godbless

edit: BTW i also have ArmorAll auto glass cleaner? can i use that as well? if yes, and then the steps would become..... wash, rinse, GS glass scrub, ArmorAll auto glass cleaner, GS Rain clear?
