Iv seen lots of posts on here about poeple having probs with air bubbles in your graphics after fitting ,Well here are few ways to help you sort out this problem
(1) Make sure that both, your hands an plastics are realy clean wash your plastics in worm soapy walter clean an dry them well
(2) Befor peeling off the backing on the sticker show it up to what you are sticking it to for size. If over lapping anywere this is the best time to trim the stickers
(3) Worm up the back of the sticker with a hair dryer or heat gun, This will help the sticker to bond to the plastic ,It will also help wen sticking as the graphic will then give more an strecth
(4) Only peel off bit by bit of the backing of the stickers you go. Get the first bit of the sticker stuck down an lay the rest of the sticker over the plastic to check for fitment. If ok you can then press on with the rest of that sticker
(5) When pushing the sicker on the plastic to get it to bond, all ways push down in one direction an then always in the same direction as this will push all the air bubbles one way an will all come out together
(6) After sticking the graphic to the plastic worm it back up with the hair dryer or heat gun to worm the whole thing back up, Then go over the whole pannel pushing down hard to make sure all of the sticker is suck down real good. Then wipe over with a wet cold cloth this wil help set the glue off .
hope this helps ,chris
