    the brand that I buy are already etched and alodined.

    It's the brand you should buy, too.

    rattle can works great if you don't have any left over polyurethane paint from the latest cover job.

    I kinda winced when I read that... I've just spent many days doing that unpleasant job, but I'm doing floats, and they're about 99' long & 77' around. I'm through the alodyne step, now to leak test & seal 'em, then the paint (lacquer). That rhymes with liquor 'eh... I need'a'nuther drink now that you've reminded me.

    Like Dave posted, they are ready for paint, no primer or anything else needed. I tape a piece of green tape upside down and set the VGs on it. Double sided tape would probably work well to if the stick-em doesn't transfer.

    Mine were rattle can painted as described 12 years ago, and nine years of that, they lived outside.

    Paint has oxidized just a bit on them, but still not bad after all these years.

    You can tell how long mine have been on!

    Actually, a guy here is a dealer and installs them for me, much easier.

    thanks for correcting me

    Chris,

    acid etching and alodyne(sp?) process is done with chemicals that are purchased from your paint supply house.

    It was taught to me that you take the acid and scotch bright and scrub the aluminum real well. The acid will foam.

    You then use clean water to rinse and negate the acid.

    Let dry

    apply alodyne to aluminum and let dry...

    However, as corrected above, the VG's come pre coated, so ready to prime.

    I was told that with the Micro VGs if you are using a yellow to be sure to prime them 1st, otherwise they tend to have a green tint. Haven't tried it yet, anybody else have yellow MicroAerodynamics VGs?

    Theirs are already alodined.

    aviation info, mine are Micro, they are yellow, and no they didn't turn greenish. That was a number of years ago, however, so maybe they've changed their process. Mine were not primed when I got them, just alodyned and acid etched.

    Yeah, for sure never let alodyne dry on the parts. It should be rinsed off with clean water while the alodine is still wet on the part. D

    Ok, I'll broadcast my ignorance here - again -

    What happens if you let the alodyne dry?

    Paint a light coat of white and then yellow. I use white over silver and then color and I use a white primer over metal. Helps bring out the color and takes less paint.

    I heard from 'them' (yeah, whoever 'they' are) that if you allow the alodine to dry, it will actually promote corrosion. This may have been mentioned in the tech info. for the etch/alodine process.

    I put a set of rattle can painted Micro's on my Husky amphib. They were still in good shape 7 years later when I sold the plane. Bill

    paint VGs

    Banner tow pilot,like Steve said masking tape sticky side up with tape about every foot to hold it down, place the VGS on the tape, than I self etch primed them and I painted them blue the color of my stripes,the plane was lite grey so the blue VGs looked good against the grey wings. Pat

    PS I used enamel from auto paint store, they matched my color and can put it in a rattle can for you alittle more money but worked well.

    And, when you glue em on the wings, use twice as much glue as specified. Never had one come off.

    You lost me there Mike. Never seen the amount of glue specified. If you use too much it squirts out all over the mask and makes a big mess to clean up and all the clear glue you miss turns yellow when it dries and really looks bad.

    I have made tiny 'notched trowels' that I derived the notch size from trial and error to place exactly the proper amount of glue each time with no muss or fuss.

    I use a q-tip to apply the 'primer/catalyst' to the masked/template area and am able to avoid spraying that stuff all over.

    PS I 'heard' from 'them' (not the vg folks) that using 'self-etching primer' over an already etched/alodined part is a bad thing. I recall 'them' saying it promoted corrosion to do so. Wish I could remember where I got this 'information'.

    Steve,

    The set on my airplane specified verbiage like "Use the minimum amount of adhesive".

    My point wasn't to use so much that it seeps out everywhere, but rather get a good coating of adhesive between the VG and wing.

    Sorry, wasn't specific enough.
