<p>Hi Phill,</p>
<p>The first method you mention here is similar to that a friend of mine used on his RV7, but he said scour with methylated spirits. He carted his RV off to an automotive spray painter and they used a two pack.</p>
<p>A paint seller I questioned advocated the Alodine, citing that's what RV builders do, but remember, they are built with 2024, which is Alclad, different to the 6061 we are using.</p>

<p>I will assume that we are prepping 6061 T-6 alu. the right way would be to etch with alodine 1200S red scotchbrite and water to get your water breakfree surface, apply alodine. let dwell to a light gold tone. rinse throually. NOTE: its much better to do this process on parts prior to assembly to avoid alodine becoming trapped in areas where you cannot reach to rinse.</p>

<p> </p>
<p>just prior to prime, a wiping with .a light solvent isopropal alchol is fine....lightly tack than prime. best to use a good two part epoxy polimide primer most need to be top coated with paint within 8 hrs of priming.. </p>
<p> </p>
<p>If assembled and you have to alodine a one step alodine can be used.</p>

Hi guys<br />
Thanks for the advice and motivational comments. I have decided to scour with the denatured alcohol and rinse with the the alcohol and slightly acid tank.water followed by a wipe down with thinners and alcohol mix just before paint.<br />
<br />
Once again, thanks for your help and I will post some pics when I have something to show.<br />

<p>Hi Phill,</p>
<p> </p>
<p>Like you I wanted to avoid alodine etc for obvious reasons. What I did stumble upon at my local aviall was a product called PreKote surface pretreatment. I've been using it to prepare all my parts before painting and it seem to work great. The whole process is very easy all you do is spray it on the part with a normal household spray bottle then scrub the surface down with scotchbrite. You then wait a minute do the same thing again then rinse it off with water…</p>

<p>Like you I wanted to avoid alodine etc for obvious reasons. What I did stumble upon at my local aviall was a product called PreKote surface pretreatment. I've been using it to prepare all my parts before painting and it seem to work great. The whole process is very easy all you do is spray it on the part with a normal household spray bottle then scrub the surface down with scotchbrite. You then wait a minute do the same thing again then rinse it off with water and let it dry. It foams up like soap when you scotchbrite the aluminium and looks as though it turns the aluminium oxide black like when you use rust convertor on steel. Haven't had any parts sitting round long enough to know what it's like long term but they say in there promo that the us airforce now uses it so I figure it must work quite well. It was about $60 to $70 dollars for the kit which included a 1 gallon/3.8 litre bottle which looks to be enough to do a whole aircraft. The mob that produce it are called pantheonchemical who have a website pantheonchemical.com. </p> just paint the bloody thing

<p>6061 Aluminum is corrosion resistant and can be polished. The link listed offers some products that might be useful, just in case.<a href="http://www.stewartsystems.aero/catalog/3afff6e7-8eea-4019-840d-f362c7eac806.aspx" target="_blank">http://www.stewartsystems.aero/catalog/3afff6e7-8eea-4019-840d-f362c7eac806.aspx</a></p>
