Well $500 is alot of cash for just the hood.....I paid over $400 JUST for the material in the Headlight / Hood/ & Bumper Kits... so $500 installed for JUST the hood is a fuking ripoff... but $500 for hood & headligthts etc is possibly not a bad deal... but installation of the hood/ headlights & fog lights is VERY EASY... & the material cost is only about $200 for hood & headlight kits , so $300 additional for install is a joke.... the install is CONSIDERABLY more difficult on the Bumper kit, & so if your installation quote is for a bumper kit... & say a hood kit../ that is not so bad....
installation estimates locally here in LA were $200-$250 from all installers i called.

.. so i did my own, all 3 kits & they turned out pretty well... the BUMPER was the only part that was not easy but if you have basic hand/eye, & perhaps some creative/artistic skills, & read the instructions carefully while preparing yer installation materials properly you can do it!
Yes you can see the line slightly on the Xpel kit for the hood, but it is VERY subtle & many times/angles you cannot see it at all... PLUS ... it is a VERY insignificant 'price to pay' for the protection it offers... i went 14 months & 23k-24k miles PLUS, with xpel on my car, installed within a week of purchasing the car, & it looked PERFECT still untill i folded the hood in my accident 6 weeks ago... would you rather Fret over a slightly visible line on your hood that ninety percent of people would never see.. or would you prefer to save the $500+ it will cost to properly paint & paint MATCH the hood/bumper to the rest of the car & have to spend that pretty much every 12-18months....??
& if you do the entire front end, you WILL NOT have to paint the BUMPER as well as that thing will DEFINITELY get hamered if your hood is getting chipped....
Xpel or any other 3m based clear film protectant ROCKS!!!
U got two choices:
1. buy & install Xpel NOW & save headaches & repainting costs later on & pretty much for the life of the car or at least the duration of your ownership of it ..../
2. Or... save the $400 $500 bux, & spend much more later on as you need to paint the hood & bumper again & again & they will NEVER pertfectly match the rest of the car....
it's all up to YOU...
& yes factor in the cost of repainting the front of the car NOW & getting it perfect so you have something WORTH protecting....
