product amt depends on what size vehicle you do...I was doing chargers and having a tiny bit left in the 30ml bottle (enough to do probably another hood or roof).....cost...well..good luck getting people to discuss their prices on here..lol....I can tell you that if you use GTECH CSL , you will need to toss at least 4 microfiber towels and two micro suede applicators....I factor in the material cost and the labor hours to apply it POST polishing- I do not sell coatings unless they purchase polishing and if they bring me a car that doesn`t need polishing I`ll probably not know what to do-lol.....it takes me about 2.5 hours to apply CSL to a charger (but im kind of slow)....you just have to figure out what your time is worth and what you can get $ wise in your area....I have people call me for coatings I display on facebook and when I tell them the price, there is that awkward silence moment....I made a few mistakes on pricing up front - especially with CSL and it bit me in the arse so I`m not making that mistake again...if you want a multi year coating--you`re gonna pay good money for it if you want this guy to install it (at least that`s my thought process)
