Over on the Spectrum Build Blog thread, I inadvertently started a (hopefully) short discussion on sail cloth as bumper material and the possible use of this dry film lubricant as a spray on friction reducing treatment.
There are some questions about whether this violates R10 or whether this violates the bumper construction rules (i.e. the lubricant constitutes something other than fabric material and therefore can’t be used). I have had some experience with this product for other applications and when it is dry, it will not transfer onto your hands or other materials. So, I believe that R10 is not violated. I also believe that this does not fundamentally change the fact that the bumpers are fabric construction. However, I plan to ask a clarifying question on the Q&A as soon as I get around to it.
Pertinent to this thread, this film lubricant may do a really good job of preventing the power cell balls from sticking to the bumpers and then rolling under the frame. I don’t have any of the product right now that I can try and I also don’t have bumper material yet (I’ll be ordering that this weekend). So, I will not be able to test this any time really soon. I know this works well with sail cloth, and I would expect it would work pretty well with other fabric materials. If I get a bottle of this, we may try it on last year’s bumpers to see how well it works on that fabric.
