On the Model 3, Suntek Ultra PPF with Gtechniq Halo ceramic coat, which is purposed made for PPF:
HALO Flexible Film Coating
The installer insisted he do the coating himself - he ‘included’ it in the price (probably as he is establishing himself against a much larger player in the area who does XPEL).
He advised to reapply every 2 years & to not use any other applications as it’s totally unnecessary & counter acts the effect of Halo
As for the film itself, he is going to be hiding the seams wherever possible by removing side blinkers, side mirrors, window sills, taillights, etc. I just read in another thread on here how dirt builds up along any visible PPF edges/seams - seriously consider paying extra for hiding the PPF edges
I use a pressure washer - if you allow $15 for a hand car wash, it pays for itself after 50 washes. I have the Gerni top end one which has the soaping mechanism built in, rather than a separate add on dispenser. 7 year warranty:
Gerni 2400W 2320psi Pro 160.2 High Pressure Washer
5 litres of car wash costs $15 at Supercheap Auto when on special:
SCA Heavy Duty Superwash - 5 Litre
You don’t need wax based wash - PPF & ceramic coat negates the need
I intend to own this car for 20 years - if Tesla get the car fully autonomous then that does the job of transport, without polluting
