My system was deburr, scotch bright,  prep-all, prime with HVLP using  

variprime.

Also called 'aluminum bright' in hardware stores ..... and 

it can be brushed on besides dipping.

 Alumiprep for about 3 minutes, then rinsed with cold water.  The etched

 surface should be primed or alodined within 8 hours.

You first need to consider your need. Are you near salt water? Other

corrosive atmosphere? If so, maybe  alumiprep etch, alodine, 2 part

epoxy primer is appropriate. Especially if you are aiming at 50 year

or more life to your project. If you are like some of us...in

Aridzona, over 60, no heirs gonna get their paws on it, a 20 year life

is plenty and with out corrosive air, the Nappa/Sherwin Williams

self-etching primer in rattle cans, over a clean, lightly scuffed

alclad on metal to metal joints is more than enough priming.

Some certified planes were built with no primer at all on the interior

and only had polished aluminum exterior with a few trim stripes, over

60 years ago and are still flying. So it just depends.

Flip your shop upside down and put it on the other side of the world where it is now summer. You wouldn't be able to even go outside for more than a few minutes in their winter.

  

 If you work faster you will generate friction with the air around you C generating heat and you will also finish your project faster than the rest of us.

Hi Kelly,

	Curious, where did you find these lifetime figures for the different

priming methods?  Can you point me at a web page or something?  I'd like

to do a little more research into this.



Thanks!

I had one of those certified airplanes - a 1947 Cessna 140 which I owned

from 1998 to 2002.  No priming of any kind and no corrosion after 55 years

of service, including many years tied down on the North Carolina coast.

Convinced me that primers just add weight and little else.   I'm building my

-10 with alodining but no priming.  Jonathon Bryant is building his nearby

with every surface primed.  As soon as I get my wings built up through the

leading edges riveted to the spars (which is where he is) we will weigh my

wings and his with the same scales to see if the weight savings is

noticeable, and we'll post the results here on the forum.



(We needed a good primer war - haven't had one in a long time)  Let the

flames begin!

Last night decided that Houston is the best “coat city” in the country.  People don’t spend money on coats here, so there’s not a whole lot of fashion when it gets cold.  

   

You see coats coming out of the closet that haven’t seen daylight since 1973.  Butterfly collars, sheep skins on the outside and wool on the inside.  You name it.  One guy reached into his pocket the other day and found a receipt from 1981.  (Okay not really, but you get the idea.)  J  

   

There are other folks who are wearing coats that fit perfectly when they were 18 years old in Nebraska, but not so well at 42 in south Texas.  It’s funnier around here than you can ever imagine.  

   

Just this afternoon, I shut off water to two houses on our street who busted water pipes.  I’m sure their owners will be upset when they get home, but hopefully I saved them a little cleanup work and a smaller water bill too.  

   

I might make another drive down the street to see if I can pick up a few more broken pipes.

Corrosion-X and ACF-50 are pretty pricey for me.  I'm going 

to buy a gallon of Boeshield, cut it with a suitable solvent 

... which I haven't figured out exactly what that is .... 

and spray it in place of the high priced stuff.

 I'm leaving most of the aluminum in shiny Alclad, because

 I plan on using Corrosion-X once it's painted & flying.

 However, there are always worked over pieces that need

 some primer. I use a rattle can of Napa 7220, which is

 one of many brands of self-etching primer out there. It

 contains MEK, so I wear long sleeve shirts, nitrile

 gloves, and a real respirator with ventless goggles. John

Based on inspections and maintenance work I've done on aircraft dating

back to the post WWII boom through the mid-70s. Nothing scientific,

just observations. Cessna especially, did almost no interior priming.

Only those aircraft based on the coasts are likely to show corrosion

to any extent. I owned a '53 C170B that lived its early life in Long

Beach where it got some light corrosion. After that nothing changed

over the years I owned it(23) and it currently is registered in OR.

That doesn't mean all aircraft will escape corrosion in that time

frame. I'm just saying that if you are aiming for multiple decades

corrosion free, you want to do full treatment. If on the other hand

you aren't near a coast and only want the plane to last as long as you

have a medical, then no point in wasting time and money on it. It may

last 50 years with no primer...but it may not, especially if it sits

out on the ramp in the weather.

Having served in Antarctica, I can say you are comparing Apples and Oranges.  Houston is in the middle of their Winter and Orcadas is in the middle of a Summer Heat wave.  Just wait a month and watch the change.
