it just a liquid how is there installation? dont you mean 'applying'? i understand laying down a coat too thin but how can prepping affect the longevity of the product? i dont get it.
since im doing headlight restoration as a business and not as a consumer is there an option to buy this in bulk to get a better deal? i wouldnt mind spending a couple hundred bucks if i new i could get a good quality 'wipe on' coat for <$4 per car. if not, what would the cost on average to coat 2 headlights?
