My dad and I spray the bunkers with a silicone spray…….heavily. It hasn’t caused any problems whatsoever and works very well. My dad has voiced that he’d like to follow up with a thin coat about every other trip just to keep the “slick” up to maximum effectiveness but I’ve found it helpful for about 25-30 launches. Of course, the weight of the boat makes a difference too.
I could be wrong but I thought someone posted some time ago that they tried “roller bunks” before and didn’t like it. Might have just been a conversation I overheard too but in that regard, it would be nice to talk to someone about their pros and cons…………..Anyone?
