Restoring an Old Spam Can -- To Strip or Not to Strip
What's the weight penalty for not stripping an old 172, just painting over
the old paint, after sanding it first, of course. I'm new at this but willing to make a go of it. I'd like to use a high-gloss polyurethane and some bright colors. TIA for your advice. I've been receiving a lot of priceless advice in this forum lately, and in a yahoogroups forum. For which I am grateful. BTW, the top done on the O-300 has been wonderful. Millenium cylinders, rocker arms rebuilt. The engine has around 8 hours and hasn't even used any oil. I am impressed. The rings are seated now and she has all kinds of power. Well, at least for an O-300. After flying a Taylorcraft the flaps are fun too. And so is flying at night. |

I'd like to use a high-gloss polyurethane and It depends on what paint you use, but I'd guess 10 - 15 lbs would be added to the plane. What you're proposing to do is why I don't like to buy planes that have been repainted. Weight is weight and someday you'll want that extra amount back and it will cost a lot of money to strip and refinish again. So, if you're doing it yourself take some extra time and do it right, you'll be pleased at the results. |

Once you see what the Poly paint is going to cost you, the question becomes, do
you really want to put that much money over old paint. Best to start with bare metal. IMHO. Lyman |

For which I am grateful. From a standpoint - if you are going to paint the plane, it really should be stripped first. There can be corrosion under the existing paint that you will not see until it bubbles up the paint. As a side note, if you try to sell your plane in the next few years, anyone buying should be asking how the paintjob was completed, and if you have proof (pictures/video) to verify it was correctly stripped, etched, alodined, primed, etc... |

Fact: the W&B done after a 2nd coat was added to our plane, is 30 lbs more. Our plane probably has less painted surface area than a C172 (same max gross weight, I think the wings are shorter, more window area). We would welcome having that 30 lbs back, believe me. And of course, if there are any flaws in the underlying finish where it is not simply weathered, but is not adhering properly or has a lot of silicon impregnated through it from extensive use of silicon-based waxes and polishes, those flaws will reduce the life of the 2nd coat. FWIW, Sydney |

It works out to more like 30 pounds, Just try to wrangle a good ice stripper(its not to messing the ice particles melts when your done, and you just sweep up the paint after a day or so. from someone using that to remove the paint. It will cost you a few hundred more (4 - 5) |

Anyone know what the going rate for a paint job is these days? For
argument sake, white only, no trims. aircraft paint over full strip down & paint -------------------------------------------------------------- c150/2 ? ? c172 ? ? mooney ? ? cherokee ? ? other low wings ? ? Just trying to see if I might get into this business. Always wanted to be in the aviation business. Thought painting might be the one w/ the least liability. Thanks, Bryan "The Monk" Chaisone |

Probably a pretty safe bet. However, a friend of a friend of a friend took
his airplane to some knucklehead auto repair types who had no experience with airplanes. They offered such a good deal! "Sure we can do an airplane....just like doing a car!" They thought it was the cool thing to just sand the airplane down to bare metal. They did him the added favor of making all the rivet heads flush. Complete disaster. So, as long as you don't do anything completely bone-headed like that..... "bryan chaisone" wrote in message om... Thought painting might be the one w/ the least liability. |
