I have been a loyal Prolong customer for years and use their engine treatments on all my cars. I tried applying this product to the mating surfaces of the Santa Maria grill and found that friction was significantly reduced. This stuff might work too well, I need to tighten the friction spring. Incidentally, the spray pump/nozzle shown in the picture was not included in the scope of delivery. In a way, I'm glad that didn't happen because it would just waste this product on overspray. I ended up buying a couple of needle oil bottles from AMAZON which are great for more precise application of this product.
