a few points to remember that will help you when making a decision
about paint protection.
Lifetime Warranty - Even the best technology on
the market can't cover you for a lifetime warranty without certain
requirements. In order for the company to offer such a guarantee,
it will require periodical maintenance. This will usually be an
annual service that will include a fee. Most likely it will involve
the dealer reapplying the product that has worn off over the year.
This is OK, if it's what you want of course. But you need to be
aware of such requirements and follow them to maintain your warranty.
And maintain your protection! Most products offered barely last
6 months let alone a year.
2. Protection From Bird Droppings etc - tree sap,
bird droppings, bug splatter needs to be removed as soon as practicable.
It is highly corrosive and will etch and damage your paint. To this
day the technology to completely protect your paint from such impacts
is not available. Paint protection products are "resistant"
to these type of issues, but nothing is bird bomb "proof".
In bad conditions, bird droppings can damage bare paint in a matter
of minutes. Paint protection products will provide you with a number
of days to prevent damage, maybe even weeks for the exceptional
products on the market. But eventually if you don't do regular maintenance,
it will eat through.
Scratch Resistance - for dealership applied products
you can totally disregard these claims. The PFTE Teflon sealants
are nothing like your frying pans and no better than some DIY polymer
sealants. New technology "coatings" such as the glass
coatings from Japan or the aftermarket clear coat produced by Optimum
Polymer Technologies are a number of microns in thickness and have
been proven to improve scratch resistance. You won't find these
at your car dealership though and they are also scratch "resistant".
Not scratch "proof".
