3M makes a product called Scotchcal. It is awesome stuff. I have had it on two cars now. There are kit manufacturers that make specific pieces for each car. I have the Stoneguard kit on our JWagon.
It really works. It won't stop dents, but it will certainly preserve your paint finish, and bras are a major problem in foul weather as they can cause more damage to the paint. Zero maintenance, just wash, and wax as normal. Can easily be changed if it gets damaged as well.
I say 'go for it' BUT find out what they are doing. I had the following pieces done:
hood (two sizes.. I got the large one)
headlights (heavier material used here)
front bumper (3 piece kit)
side mirrors
sides of fenders near headlights
I had custom made panels for:
door jams
doghouse in front of rear wheels
It is an art to get this installed correctly, and the price you got quoted is very cheap. I paid over $700 CDN to get all that done on our '04 wagon. Took about 5 hours to install.
HTH,
Harry.
