its all in the prep , it took a pro a day to prep my tub, not for diy.
but dont forget its paint it can be damaged and you have to be
carefull on cleaning. With a large family forget it, it will be
ruined but for one or 2 carefull people it could be ok. Its a job where
you easily could get a contractor to not do it right and have it fail.
Its all in who you hire. Get refrences at least 6 yrs old. You realy
only want old refrences and alot of them.
