If anyone in KL, Melaka or JB is interested in getting their car tinted, I recommend to check out Alva Concept Store. They specialize in car tinting, coating, painting, but they also sell car accessories as well.
Prices are reasonable and they're currently having promotion ~50% off their normal prices, with warranties ranging from 5 years to lifetime warranties!
Got my new Myvi 2022 tinted using Alva DY series that is from the US and using nano ceramic film with lifetime warranty at ~RM1.8k (normal price is 3.6k), IRR 98%, UVR 99.9%, UV block 400nm, 4mil security film (this is their highest spec tint).
Verified the specs using the infrared scanner machine post-tinting and turns out to be true.
Also GPS and SmartTag-friendly (verified on NS Highway).
P.s. You can use my code "JVD7250" for an additional 15% discount.
Feel free to PM me for further enquiries!
