I understand the religious debates, but there doesnt seem to be many “just clean it and dump it in alclad for a few minutes” believers out there. Don’t leave the part in the alodine too long.

No registered users and 1 guest. Some that are sheet metal specialist. How are you guys disposing of your spent alumaprep and alodine?

Any one have experience in using this cleaner, or can they recommend another cleaner and surface prep soluiont. The alodine is really needed where there is no corrosion protection. I guess metal prep is a real sensitive area. They alujniprep prep 33 and alodine all the time. Then they put a 2 part epoxy primer on.

A few suggestions about it’s use: Keep the part wet between alumiprep and alodine. This alumnirep the stuff of primer wars. It will turn out fine. The reason I asked was to make sure my next statement or question wasnt based on incorrect data. The bottle states not to use on high copper alloy aluminum.

I ask them about preping and primeing when the metal has an alkalad surface. Don’t leave the part in the alumiprep too long. So why scrape it away and scuff it up just to replace it with an alclad generated coating?

Nothing wrong with that as far as I know, but if you get it right, the alumniperp almost looks like it’s anodized. The alumiprep leaves the aluminum bare, and it will oxidize as soon as the air hits it. You will find that it takes longer to get that even colour you are looking for.

Using Alumiprep 33 before Alodine –

They said 2 reasons. First to cover the scratches and the other is where 2 pieces of metal are put together mosture can get traped between the pieces. It is pretty much all I am doing. If the part is starting to turn dark, that’s too long.

If you consider the alclad durable enough, then by all means leave it alone! Only time will tell who is right. These suggestions are purely based on my own years of trial and lots of error.

You’re eating up metal at that point. Then you have the temper number, ie.

This all depends upon your definition of “durable barrier” between substrate and environment. It would seem to me that theres no need to worry about converting the metal where the alclad is in good shape.

Just follow the instructions for application. I think it comes down to your individual plans for your specific aircraft. But the normally recomended cleaner is Alumiprep Alclad is a top layer of pure aluminum applied to the for corrosion protection. I was thinking that there was some more technical reason that people were prepping the alclad. It will come out with a “chalky” tone too it.

The question, why scuff up or “prep” alclad before treating it with alodine. After you rinse off the alumiprep, don’t let the part dry off.

Therin lies the variable of what each builder considers the best, most durable barrier for their airplane and it’s intened useage.
