i have seen shops with the carts,with all the supplies,on them.i have another one,that i keep extra supplies and othe chemicles on,so i dont walk far to fill,or get something else. i change some items by what i think i may need per vehicle, ie stain removers,extra tar remover,etc.even a cople extra bottles,incase i drop one,and it breaks. just something that i hope,helps others.
