one problem i have noticed by seeing peoples creations on plastics witht he spray.. is the outcome depends on the persons ability to control the spray.. ive seen peoples stuff come out messy.. and they used very light sprays.. (spray, dry, spray dry.. etc..) what i mean by messy.. is it doens't look even like the rit method produces.. but if your good.. it will look even.. if your tinting a pos canapy.. try the paint.. and see how yo do.. or on a scrap piece.. but for the big $$ stuff.. your have a better chance of good results with the rit.. you just need to grab the things between your legs and do it.. =)
