 Posted: Wed Feb 02, 2011 10:23 am Post subject: painting a plated engine mount frame |
 |
|
my FWFD kit from europa as well as other manufactured parts that have arrived recently are plated with cadmium or something similar- bits like the engine mount frame. Can anyone tell me if I should paint these and if so, is it ok to use the normal aircraft metal etch primer. I would then add the normal two pack poly paints.
ALSO, I am still not clear whether it would be a good idea to coat the firewall GRP with sticky backed foil/insulation or foil of somekind, I have seen something like this in some of the pictures.
Help appreciated.

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]--> Just an opinion,
The aircraft with the anodized frames are holding up very well without paint. Nose gears and mounting frames are doing well also.
I personally would not paint the frame. Use ACP 50 or similar anticorrosion coatings on your annual inspections and it is fine. Inspections are a breeze as you don't have to inspect every crack in the paint for problems.
Please note the the pros of painting are it is easy to clean and brightens up that dark hole. Follow the paint manufacturers prep instructions. Powder coating is good on steel, but powder coating of aluminum should be monitored as the temper of components made from aluminum could be compromised if excessive heat is used in the process.
Whether you paint or not, do not use metal clamps or zip ties directly on the frames as that will cause wear of the protective coatings and start corrosion.
Please use WDG (aka Adel )clamps or other rubber coated tight fitting clamps to prevent paint/anodizing wear and eventual corrosion. If you must use a wire tie strap or zip tie, please use rubber tubing or similar as a cushion mount. Just slit and place your short piece of hose over the frame tubing and then attach the zip tie around the hose as the mount. Then use another zip tie to hold the component or wire snugly to the mount... Do not allow components to rub up against the engine frame or gear frame as unchecked, corrosion can cause eventual corrosion or structural problems and costly repairs.
I even use stainless steel straps Reduxed on the gear frame for mounting the nose gear springs to prevent eventual wear. I am told they have homes for people like me. But it works.

Hi Graham,
In my book, extra firewall insulation and additional painting are optional
extras. I think the old adage says " when deciding if an optional item is
worth fitting, toss it in the air and if it falls to the ground it is too
heavy to fit" Weight is the real enemy of aircraft performance.
I learned this the hard way and have lots of nice extras, but my wife can
take hardly any baggage on our trips. My stuff is essential, of course.
Regards
Brian Davies

Hi Graeme,
The parts you have are zinc plated (I believe the drawing calls for 'ZN8-10 CHROMATE PASSIVATE AND TOP COAT').
So, you don't need to paint these as the coating will protect them.
However, as Bud says, it is very easy to scratch this coating when working with the parts. If you do scratch anything then I'd touch up with some zinc rich primer or something like that. Also, as Bud says, the ACP 50 stuff is very good and a light coating of this will protect the parts.
Phil
