Hi, I just tinted my ride a month ago with 3M Crystaline70 at a shop which is a distributor of 3M and I can assure you good service and most important good workmanship at this place.

FYI, I did the same as what u doing now, search for some recommendation and review for tinting film, and came to know to know someone that did his tinted at the same place.  Visited a few places, and end-up tint with this shop...
The owner himself and his brother will do the tinting job themselves.....

so if you interested, let me know, will PM you the address and u pay them a visit and talk to the owner himself, no obligation.... proceed only if you are satisfy after talking to the owner  ok 

3M tint pricing is close to vkool?

for my avanza
it's rm1800 (with rm200 discount so i paid rm1600)

crystaline will be 2200-2300

but crystaline is security tint rite?

Tmn Maluri behind Jusco near to Public bank...

Did whole car, Crystalline 70 windscreen and Crystalline 60 the rest. Pretty good stuff, too bad it's not smart tag friendly.

Just wan to know if 3M will get rusty like vKool.

this is what i heard from a friend of mine working at 3M tropicana there...

he used to use 3M tint on his vios (employee can get better pricing)

after a few years, he changed to huper. I asked him why he changed cause i was also thinking to get 3M for myvi and my friend told me that 3M tint will shrink (especially the front windscreen)

I am here not to flame or endorse any product, just stating what my friend experienced...
