Thanks to all that have posted. I have received some really great information over the years on this forum. The best advice was to buy a Prodigy Brake controller. What a great difference that made. That was my reason for asking about the teflon spray. It sounds like few people are using the teflon to just spray and go, which makes me wonder about its benefits. I have to believe if it was that easy, the folks on this forum would already be talking it up. Being a "greaser" for many trouble free towing miles, I guess I'll just have to stick to success and keep greasing, and work a little harder at staying clean. Thank you.
