I'm SO DONE with applying firm!
I just received my Bodyguardz in the mail today. I order the B.G. (even after my Best Skins Ever one has already been shipped) because after checking out the forums, I realized that B.G. ones got the chrome part covered.
So the trickiest part is:
1) Lining the firm up. Especially the left and right side, making sure the entire chrome is covered.
2) Keeping the dust away.
I ended up using BOTH sheets. For the 1st time, the sheet is placed more to the camera side (instead of the volume button side), hence one side of the chrome is not completely covered. As I wanted to use my iPhone with this shield on ONLY, after some hesitation (as it was getting close to my bed time), I decided to do everything againi to make sure that I got ALL of the chrome part covered.
After knowing how the firm is cut, I managed to line it up "perfectly", except that this time I wasn't careful and patient enough and I quite a lot of dust under my B.G. (probably because it'd took me some time to line things up perfectly and dust happened to slip under the firm as time went by).
So I got the first one, 90% perfectly lined up, and almost free-of dust, and the 2nd one, 98% lined up, but with a few noticeable dust-spots. Am I going to get another firm? Yea, I will get one for my future replacement (my I.S. on my MBP is turning yellowish) but I'm going to settle with what I have for now. I'm a perfectionist but I really don't feel like spending so much energy, HOPING that my next application will be better than the previous ones.
Tips:
1) Get the firm WET! WET! WET! (so that you can realign it again and again)
2) Clean your work area first! (you can be lazy, but you are going to live with the dust that is buried underneath)
3) The firm is cut so precisely that there is no excess part to any side of the chrome. Make sure that you don't line the firm a little more than you needed to cover a side, otherwise, you will realize that there isn't enough firm to cover the other side.
P.S. I have applied a Invisible Shield on my MBP and two iPod Touches and one Best Skin Ever on my Apple Remote.
