The SEM instructions were a little confusing for me - but the prep spray is different for plastic vs vinyl. You're supposed to clean it well with their soap (i did it a few times), then apply the vinyl prep, then paint after/within a certain timeframe. Read the instructions a few times.

Honestly I was really impressed with the result, great product. I would buy SEM, who knows what year one is pedaling.
