No reducer - Use a clear coat that you have to mix - not a spray can. The activator and the clear coat seem to be fairly friendly to the decals but the reducer seems to have a violent reaction sometimes. "
What is "reducer" and what is "activator"??
It's nerve wracking and exciting! I am so glad you are sharing your experience. I will be doing one eventually and although "it's just paint" ugh...who would want to let it all dry and start over? 
My thoughts are even if mine doesn't come out perfect...it will surely be better off than it is now. I'll be waiting until I have enough info and the weather is more stable. I have heard that a lot of humidity isn't great.
