That's because my wood is protected by the finish. I believe you also boat in the north if memory is correct? Big difference north and south. |

Charlie, either your experience with varnish is with a horrible formulation, or you just don't have any. Quality varnish, such as "Flagship," has very high UV protection. Properly applied to properly prepared wood, it will protect extremely well. Nor does it have to be "scraped and sanded off every time you want to refresh things." Scuff the surface, clean, apply varnish topcoat, Bob's your uncle. If scuffing and cleaning the old varnish is too much for you, combine some Penetrol with the varnish and you don't even have to do that. Yes, varnish requires maintenance. But so does Cetol, for that matter. There is no substance known to man which can be applied to wood which will then forever protect and keep it shiny and pretty. Everything wears out over time. As an aside, UV protection does not require opacity, nor does opacity guarantee UV protection. I had a conversation about this with a chemical engineer from a paint company. Varnish fails because UV damages the wood underneath, destroying the bond. The more transparent the UV protection, the higher the cost, which is why cheap varnish fails quickly. Cheap varnish has either less effective additives or less of the good ones. Enough of the good ones is expensive. Classic Cetol uses iron oxide for UV protection, which explains the orange color. I imagine it has other additives too though, and the "Light" version less of the iron oxide and more of the transparent stuff. After using both Cetol Light and Deks Olje side by side for two seasons, we've switched all the exterior brightwork to Cetol Light. I was quite surprised how well the Cetol held up, especially on the areas that weren't covered over the winter. After a two year trial, it was clear which was less work -- Cetol. Matt O. |

Then again, real varnish doesn't do much to protect the wood at all, which is why you have to scrape and sand it off every time you want to refresh things. That's pretty hard on the teak, which weathers under the varnish and then gets sanded! CWM Based on the above, you have never used varnish. Or at the very least have no idea how to use it correctly. |

If you have an opinion? Between Bristol Finish and Cetol? Cetol requires a lot less time and effort to maintain. It comes in three basic varities: Cetol Marine, which is the darkest, and most "orangy" in color. Some folks have a real thing about the way it looks. They have a lot of time to obsess about it as they sand and re-varnish every season. Cetol Light: A much lighter color than the original. Since you don';t have to sand down old Cetol to apply a refresher coat, many folks use the original for the first coat (for stronger UV protection), and then use Cetol light over it as their yearly refresh coat. That keeps the overall look from getting very dark over the years. Cetol Natural Teak: New product. Lighter than Cetol Light, and more like the color of varnished teak. I don't know for a fact, but I would guess it can't protect against UV as well as the more tinted versions. Then again, real varnish doesn't do much to protect the wood at all, which is why you have to scrape and sand it off every time you want to refresh things.

CWM- Hide quoted text - - Show quoted text - Again, that just tells anybody who does know how to apply varnish correctly that you don't. I live in Florida and have had varnished boats go up to 10 years before having to wood them down and start a new with fresh varnish. |

I've been using Interlux Goldspar which is a single part polyurethane "varnish". Eight coats and you have a beautiful clear and shiny finish. Eight coats of Cetol and you have mud. EIGHT COATS? Are you looking for excuses to avoid sailing? CWM- 12 coats is about the min. for a really top quality finish. |

You might get away with that for one extra season (if you have carefully kept everything covered with that lovely blue canvas - which you have already told us is necessary for varnish because it offers very little protection of its own) Total BS. Here are a couple of things you don't know: Clear Varnish may contain some form of UV protection or stabilization for the_varnish_itself, but does almost nothing to keep the underlying wood from being damaged by the sun. That's why you have to strip it all off every few years. The wood has still taken a beating. You're back peddling now. First you said : "which is why you have to scrape and sand it off every time you want to refresh things." Now it's every few years. To protect the wood REQUIRES some level of opacity, and the more opacity, the more protection. That's why you have to cover all your wood with canvas. I don't cover any of mine. That's because my wood is protected by the finish. Yours is not. Canvas are used to prolong the life of the varnish. And extend the time between recoating. Not so much to protect the wood. |

Coating for wood wheel (was: Cetol vs Bristol Finish)
Similar to the thread topic, I am wondering what is advised for coating
a wood steering wheel? I bought this off eBay and it is NOT one of the decorative wheels with the brass hubs. this has a bronze hub that fits my Edson pedestal and appears to be mahogany. It's quite weathered and I've stripped all the remaining varnish off. (There wasn't much left anyway). I have a sunbrella type cover for wheel/pedestal/compass so this will not be left out in the elements when not in use. What would be good coating options? I'm not looking for classic yacht perfection. In fact I'm willing to trade perfection of finish off in return for less effort in coating. So far I have two suggestions: 1) Coat 2x with product from rotdoctor.com then 7-10 coats of varnish. (the wheel is not rotted. But this fellow says the product is a great sealer). 2) Use some sort of sealer or filler to even out surface, then coat 3-4x with West epoxy. Any thoughts or other ideas welcomed. (My address is phoney due to spam) |

(My address is phoney due to spam) Wood it, 2-4 coats West or CPES, sand smooth, then 4-6 sprayed coats of two part poly. Did that to two wheels 15 years ago. The interior one still looks like it was done yesterday and the exterior one lasted 8+ years semicovered before it needed recoating. |

Charlie hasn't convinced you that Cetol is the way to go? He's going to be disappointed. For something like a wheel that is going to be handled a lot and maybe banged into from time to time you may want to go with durability and I would guess epoxy is the ticket. I think that rotdoctor stuff may just be a thin type of epoxy that penetrates the wood. There was some discussion about thinning epoxy on the list a while ago and I think you can use acetone but denatured alcohol was better, up to 10%. A coat of thinned epoxy followed by several coats of regular should do it. Don't know about UV inhibitors in epoxy but it might be worth asking about as they would help preserve the wood. |
