Glass Science question

[spyghost]

question lang po about sa Rain Clear at Glass Scrub
1. Does glass scrub remove yung part na pag tuloy-tuloy pag ulan tas nagwa-wiper ka, may part na hindi nya ma wipe na para bang permanent na basa..? (elevo water mark remover removes this, kaso ubos na yung ganun ko)
2. Paano po inaapply ang glass scrub? kailangan po ba wet ang windshield, then apply? MF towel po ba ang pang-apply?
3. Paano po inaapply ang rain clear? wet or dry windshield? MF towel for application?
4. Gaano po katagal ang tinatagal ng rain clear sa windshield?
5. Gaano po katagal bago ko po ulit gamitin yung glass scrub? does it remove the rain clear in the windshield?
TIA

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.
