Hey guys, Im going to do some painting on my car. I bought PPG paint. (the original color of the car) and got the reducer and the clear coat. my question is, what is the ratio to paint - reducer??? on my primer can they gave me the ratio of primer and harder 4-1 ratio. with this i am not 100% sure what i should mix. any input from guys who have done this before would be awesome. thanks - Jon
