Composite Prime & Paint solutions
Looking for some comments on the best choices for PRIMING & PAINTING
composite aircraft. UV protection - Easy to work with etc..... Poly-Fiber makes a roll-on UV Smooth prime for instance, so some of the finish work can be done in the garage. Thoughts folks? Thanks. |

Don't use smooth prime. Sometimes, for no apparent reason, it
bubbles up under the paint and oozes brown goo. Nothing sticks to it well. See http://www.cozybuilders.org/chapters/chap25.html and read the addenda at the end I am aware that Zetlin had bad luck with it and your dislike of it even though you do not indicate that you ever used it yourself. But to be objective and fair, there are many who have used smooth prime successfully http://www.eaa.org/benefits/sportaviation/oct_womb.html http://home.comcast.net/~ogoodwin/Mustang.html http://www.picturetrail.com/gallery/...4827&uid=91657 - including myself with the paint on for two years now. I used PPG acrylic urethane right on top of smooth prime and it sticks well with no indications of the paint comming off. PPG seems to stick to anything. ---------------------------------- SQ2000 canard: http://abri.com/sq2000 |

Luck had nothing whatsoever to do with it. Polyfiber has admitted as much. But to be objective and fair, there are many who have used smooth prime successfully You're absolutely right - many have used it successfully. But to ACTUALLY be objective and fair, you'd have to state that while 99.9% of folks that use OTHER Primer products have no problems with them, well over 10% (maybe closer to 20%) of the folks that I know that have used SmoothPrime on composite aircraft have had major problems with it and will have to refinish their aircraft due to those problems. Which system would you pick to use if you had known those statistics before choosing? -- Marc J. Zeitlin http://marc.zeitlin.home.comcast.net/ http://www.cozybuilders.org/ Copyright (c) 2005 |

Marc,
I apologize for mispelling your name. It was purely unintentional and had nothing to do with us disagreeing. And I think we agree on a lot more issues than disagree. There are some finer points where we don't think the same. Luck had nothing whatsoever to do with it. Polyfiber has admitted as much. The impression here is that Polyfiber has admitted that they know when smoothprime will fail because it is not luck but known technical reasons. However on your website " ...Top Gloss has been removed from the market, due (I believe, although Polyfiber won't admit it in public, but have said so to another builder)..." the "admission" really refers to the Top Gloss paint and not smoothprime. Thats not pure objectivity. |

If that's the worst spelling of my name that I ever see, I'm doing OK :-). ..... And I think we agree on a lot more issues than disagree. There are some finer points where we don't think the same. I'm sure that's the case. Luck had nothing whatsoever to do with it. Polyfiber has admitted as much. The impression here is that Polyfiber has admitted that they know when smoothprime will fail because it is not luck but known technical reasons. What they have admitted (to me personally, on the phone) is that the failure rate of SmoothPrime is substantially higher than that of competing products. They have admitted that it's much more sensitive to many essentially uncontrollable (and possibly even unknown) environmental parameters than competing products. This does not make it unusable - just MUCH more of a crapshoot as to what you'll get popping out the other end. However on your website " ...Top Gloss has been removed from the market, due (I believe, although Polyfiber won't admit it in public, but have said so to another builder)..." the "admission" really refers to the Top Gloss paint and not smoothprime. Thats not pure objectivity. My previous statement ("Polyfiber has admitted as much") regarding what PF admitted wasn't a reference to the website statement regarding TG, but to the phone conversation regarding SP. Hope this clears things up! -- Marc J. Zeitlin http://marc.zeitlin.home.comcast.net/ http://www.cozybuilders.org/ Copyright (c) 2005 |

my name isn't as easy to spell as "Lee"...
I like things short. Chose 416 for my aircraft number. Much faster to say "four-one-six" in an emergency than for example "eight-niner-seven-papa-lima" |
