Hot Rod tubes
"The extra smooth version of Hot Rod Tubes was causing me to cough constantly. I used the smooth dark blue version before and that actually reduced the cough. I live in Alexandria, LA and finding the Hot Rod brand is difficult. However, if I could get info on local shops that stock or if I can be an affiliate I would love to hear back. This brand is helping me reduce the cough. I have tried other brands and they are inferior to Hot Rod. I would love to hear from you. Thanks, Petra"
