Vinyl seat dye???

Thanks guys for the opinions.....I will probably end up saving up the 3 or 4 hundred and get a new set of black covers because I really don't feel like doing the job more then once. I keep keys on my belt loop and have to have a car seat for the little one and I can almost garuntee it will not stay painted.....I was told to use SEM and I wanted some opinions on it and I am glad I got them,by the sounds of it....doesnt sound much different then the dupli color vinyl and fabric spray i have used on all the rest of the interior, I was jsut hoping there was an actual dye for vinyl out there, if you guys find anything, let me know.... Thanks again , DusterDude72
