i am working over in my mind whether to paint my new CH801 myself, or hire it out. I have done auto painting, but not familiar with Aviation paints as i have hired out previous paint jobs. does anyone have any advice on type of paint, primer, acid etch, paint machine type, etc. any info or personal experiences will be helpful. thanks!
Check out the Endura paint web site. Lots of info on painting and the Endura product is easy to apply and get good results.
Probably 85% of the paint job is the cleaning and prepping of the aluminium to accept the paint.
Hi Bob, thanks for the info! josh
prep the aluminum, with red scortchbrite , and spray with a thinned couple coats of self ecth and spray with a automotive urathane. i have done it on many airplanes and not a real propblem
just make sure its scotchbrited good
I have a 701 and I would be interested to find out more how you painted your airplane.Did you brush it on or sprayed it?
Now for the basic information;
Paint and process.
The Paint I chose was ACE Hardware Premium Latex, the primer is ACE Hardware Galvanized and Aluminum Primer. There is also available a Latex Clear Coat made by Krylon,, the additional items you will need are Automotive windshield washer fluid, I am using the blue colored stuff, and a product called FlowTrol.
First I prepare the surface with a 3-m scratch pad to give me some tooth for the primer, then clean with liquid solvent. In a coffee can I put about 1 to 1-1/2" of FlowTrol in the bottom and then add primer to about ¾ to 4/5 th's of what it would take to fill the spray gun, Then I stir and add the windshield washer fluid to thin until I can get the paint to run off the stick and go from a run to a drip between 4 and 5 seconds, you may need to experiment for yourself the adjustment that works best for you.
I then strain this into my spray gun and set the air pressure at 80#psi, yes I know that is real high, I shut off the controls on the gun and then re set them spraying against a sheet of paper until I get the mix I want, then I spray the part, I use light coats and find that in using a reasonably fine mist by the time I reach from one side of the wing to the other the first part has flash dried and I can go back and add the next coat. By doing this I found the paint flowed out flat without any runs or any type of orange pealing. I laid on enough to cover the part for protection as I know I will be putting paint over it later. I use the same process with the colored paint and after only a little practice found it was very easy to put on and the results look great, but will look better after the clear coat.
Latex paint runs in the area of about $20-$30 which is a lot better than the $300 a gallon for the aircraft stuff. Now does it look as good, probably not but I was not building a show plane it is a working plane and a fun to fly plane I am not looking for any trophies.
Another thought which has come up since I did my project is Auto Zone and other Automotive stores carry the Dupli-color brand of paints, these are automotive paints of a lacquer base and are ready to use out of the can, this may be a little more costly but I am sure the end result would be a better looking, however, this is back to toxic or semi toxic materiel's and will require respiratory protection etc.
So far the paint is holding up well and as I said I expect it to do better after clear coating it. I hope I have answered your questions and have been of some assistance, you are of course welcome to come and visit any time.
