The fact that you already have installing PPF gives you a huge advantage! I researched 7-8 sites and found TintZoom to have the most bang for your buck (it comes with all the little accessories too!). You should be fine - the S4 has a smoother hood than the S5 so you shouldn't have any problems at all. Definitely be very liberal with using the soap/water solution and use the squeegee that comes with the kit. It helped a lot. Oh and do it indoors of course

Hi Carys4,

Thanks for the info on PPF. I am also interested in DIY and ordering from Tintzoom.

I did my own PPF on my Mazda MX-5 when it was new. It was the first time I did PPF and MX-5 is a bear to do with the body curves. It came out not too bad lol.

Grateful if you have any advice on ordering and applying the PPF on the S4. I plan to order front bumper and headlights.

Thanks much!

Mike
