Inputs needed: Glass Coating

[Stokedmd]

guys, need your advise. i am currently canvassing and reading reviews for service providers doing glass/ceramic coatings here in Metro Manila for my Civic. but i am confused as to which is better. i'm looking for reasonable price with good quality (that would last up to 2-3 years).

Below are the current list that I have:
- Mastermind Auto Lab - Php13,000
- Technical Details - Php8,500
- GMAN Car Care - Php18,800-23,500
- Buff n' Grime Professional - Php25,000
- Ziebart North EDSA - still waiting for their price
- Manila Detailing Professionals - Php5,500 (if within promo period, with Php1,000 discount)
- Big Bert (just added in my list based on other's post, not sure how much is the price)
- Akemi (just added in my list based on other's post, not sure how much is the price)

I find all their pictures and reviews to be fine, lahat makintab after coating. hahaha! not sure as to the experience of those who availed as to which is easier to clean after, kintab after X months, bagsak ng rain water, etc.

I am just not sure which one really lasts and worth the price? my budget, if possible, not over Php20k.

Yung sa Gman and Technical Details parehas ng price if equivalent solution gagagamitin mo. Yung 8500, yan ata yung lower end. Been inquiring too, lalo na from long term users. So far choice ko is between Brila (GMAN) and Gtechniq (Technical Details and Sprint Auto Spa). Yung Akemi parang mga casual car drivers yung nag rereview. Long term wala pa feedback.
