Waxing and polishing
I seem to recall asking Fidel about silicone in waxes.Â* He said not to
worry about it. On 3/3/2019 2:59 PM, BobW wrote: On 3/3/2019 12:08 PM, Martin Gregorie wrote: Snip... I've been told to never use silicone based polish because it is said to make repairs to fibreglass or carbon structures very difficult or impossible to repair. In fact I remember reading that here, so it must be true! OTOH I've not seen any publications that mention the effect of silicone contamination on repairability. The only article on repairing FRP structures I've seen, in a search I just carried out, that even mentions contamination in any detail is: https://compositesuk.co.uk/system/files/documents/ repairoffrpstructures.pdf It has a short section about contamination (half a page in a 33 page PDF document) that mentions "fuel, oil, hydraulic fluid, etc" and moisture, but says nothing about the perils of silicone-based polishes. The other 2-3 publications my search turned up that didn't turn out to be pushing supplier's products either did not mention contamination at all, or gave no details apart from describing how to sand through surface finish. So, what's the deal? Are silicone-containing polishes etc to be shunned? Can anybody recommend an FRP repair publication that gives any more details about dealing with contamination than the one I quoted above? Lordy, it must be winter in the northern hemisphere! Certainly there's no harm in avoiding 'silicone-ingrediented' waxes, but IMO 'commonly-held views' on the subject border on religious arguments in that 'proof of one's beliefs' is rarely part of the discussion. So while we're polling, let's not forget including FRP repair shops' inputs. My own direct shop-input querying-experience - *not* repairs, sardonic chuckle - includes a mere 3 (4 counting a long-ago RAS post by JJ Sinclair), and, so far, each puts "Silicone = Bad!" into the urban myth category. Further, who can point me toward an accident report involving structural failure of a repaired FRP glider, that has 'fingered' silicone as a contributing factor? N.B. For the disputatiously-inclined, I am NOT recommending spraying every accessible surface of your bird with silicone spray (a little common sense can go a long way), but rather positing that 'fretting over its presence in wax,' arguably falls into the urban-myth/anally-self-inflicted worry category. YMMV, of course... Bob - last night's low -1 deg F. here - W. --- This email has been checked for viruses by AVG. https://www.avg.com -- Dan, 5J |

I also asked Fidel about silicone in wax. He held up an angle grinder with a sanding disc and said it was tougher than any silicone he's encountered. But he also recommended Carnauba wax for its sealing properties.

Waxing and polishing
I have not used any hard wax product for years on any of my vehicles (cars, planes, sailplanes etc).
I've been SUPER happy with JetShine from PERMANON. It's a bit expensive but takes almost ZERO effort to apply. The activating bonding ingredient is water and one just simply sprays it on a clean surface then wipes off the excess. It is "nano-technology" and protects the surface beautifully while protecting it from UV. After using this stuff for almost 10 years, I'd be hard pressed to ever go back to hard wax and buffing wheels! https://jetshineusa.com |

For example, keeping it in great condition, smooth and shiny? |

But if you have a chance of avoiding it, please do. I wax my glider with hard paste-style Collinite. With normal "easy to apply"- fluid waxes (=most likely to have silicone) the wax wears off pretty fast from leading edges. |

With normal "easy to apply"- fluid waxes (=most likely to have silicone) the wax wears off pretty fast from leading edges. One of my chums has done some research on polishes. Most polishes and waxes contain silicone, here are the one’s that don’t. Most were checked by looking at the Safety Data Sheet. Vistal Cleaning: “One boat cleaner”. Boatsheen: “Best Brazilian boat wax” – carnauba wax blended into a cream. BulletPolish: “Carnauba Quick Spray wax” – a cleaner with wax but no abrasives. Yachtca “High gloss finish” – a polishing and waxing paste. Starbrite: “Presoftened boat wax” – based on carnauba wax but softened for hand application. Starbrite: “Marine polish” – polishes and waxes (Carnauba not mentioned). Starbrite: “Hull cleaner”. (NB Premium and products with PTEF contain silicone.) The 3M products Perfect-it Light cutting Polish & Wax and Perfect-it Boat Wax both contain silicone. Meguiars Boat/RV pure wax contains silicone, don’t know about Meguiars Flagship Marine wax. Putting the company name into Google finds all of the above. From the above info the Starbrite range or the Vistal Cleaning “One boat cleaner” with Boatsheen “Best Brazilian boat wax” look attractive. I guess the only way to evaluate them is try them? (I use the Vistal product on my LS8 and Cobra trailer to clean the surfaces prior to polishing and it works really well.) Hope this helps. Mike |

In a round about way, people are saying, "yes it's worth waxing your sailplane". They do this by stating what they use to do it.

Does anyone have any experience with the F11 product marketed in the US for cars and boats. Their website says it is silicone free.
