It's something we've talked about a lot over the years as new products came out, and I've used pretty much every product out there. One, that I've always bypassed, is Suntek. Well recently after buying a non-Viper, that dealer rep (which is a friend) got me up to speed on what they've been doing. I went ahead with it and I have to say - in my opinion it's better than 3M or xpel. I was really surprised.

I've had 3M on a lot of cars, it was always solid - I raced with it and never had a rock penetrate. On the cars that still have it, it's held up well - no clouding. Only issue I see is that edges do seem to lift more (when washing the car).

I put xpel on my newest 3 cars, and I have to say I have rocks that got through all three. Not sure if it's coincidence (as it's supposed to be 8.5 mil), but I was really surprised. I do notice adhesion seemed great, and it seems the installability is easier with it. But I did like the 3M better.

So self healing is also a feature they're all touting. I happened to have a piece of the 3m, xpel, and also the suntek. I scratched them up and hit it with the drier. Only Suntek healed completely (and shockingly - imperceptibly - I actually couldn't believe it). I took it further just to see how bad I could damage it before it healed - I can say that there's nothing you could do with a rag (including a rock being stuck in it) that it couldn't heal. Using the grill wire brush I scratch them up at various levels. I was surprised xpel (which was supposed to be great at this) didn't do as well. I used a drier but also let them bake in the AZ sun for a day. The suntek outperformed them both here, clear winner.

We'll see how well it holds up against rocks, and I must admit it even seems to have less arrange peel that xpel. I admit, was completely surprised.

Interested in hearing from those who have good experience with different products over the years. We haven't talked too much about suntek, any good feedback on it?
