Changing color on interior parts

i have dyed many panels,including seats,and rubber floor mats,the best solvent to really clean all the armour all off is any degreaser,like purple stuff,etc,with gray scotch brite pads,then rinse and dry.then wipe down with rubbing alcohol.i have just skipped to the rubbing alcohol on parts that were already clean looking,or cardboard backed,and have had great success.the sem products are awsome,but if you have a cheap paint gun,professinal dyes from companys like dupont,martin senour,ppg,etc,are the best,and dry almost instantly.they will also last much longer on high wear areas,like seats,and arm rests.thats what i use,good luck!
