The day after

So.... with the advice of a salesman, I used what we all thought would be the strongest paint to use to stripe lines on some indoor/outdoor carpeting using a spraygun. Unfortunately, all the work ( in no less than 17 hours in 95^ heat ) began chipping off the surface like powder!  Yesterday was spent repainting the entire area by hand w a paintbrush and different paint . So what is the day like after you spend another nine ours bent over painting stripes on the floor by hand?  SORE !!!!
