I just finished installing several graphics packages on my Sling.
I bought the large bottles of Rapid Tac and Rapid Prep and have enough left over to install another kit.
If you are planning to install graphics, this stuff made it fairly easy. This was my first time doing any type of wrap or graphics and it wasn't that difficult. Overall, came out decent for first attempt.
If you are going to install graphics in the near future, I would be happy to send the left-over Rapid Tac and Prep to you. Just ask that you cover shipping.
I will also send the squeegee.
Send me a PM.
