this is so so true powdercoater... if the spray and oven is not propperly done as well with propper enviroment you will get a coat with hair and other airborn crap under your paint! looks like crap... the right tools and propper prep and the peel that wide glide is dealing wth will not happen... plus on suspension if you did do paint it would have to have 100000 coats of clear on it to hold up to the elements that the underside of a truck are exposed... i shoot the underside of my Jeep every year with rhino liner and even that does not hold up like you would think (granted i am in chicago and they salt the streets... plus i crawl with my wrangler and the mud and crap does not help)
