Mike,

 

I wasn’t so much looking for alodine as a pretreatment for the Hysol, it was more to protect it from corrosion.  As you may have guessed, the hinge brackets for the forward hinge canopy in the 320/360 series is an aluminum bracket that’s bonded to the header tank, never to be removed.  As such, corrosion on this part would fall under the category of “stuff you don’t want to happen”.  My question was more along the lines of “If I alodined my brackets for protection, could it have an adverse impact on the ability of Hysol to bond the bracket to the header tank”.

 

This has been my business and livehood for about 33 years and never have had a question like this.

 

You don’t know how many times I’ve heard that while building this plane…

Gary,

Alodine is a chromate conversion that is usually applied to bare aluminum for corrosion protection and a base for painting the aluminum.  As for a pretreatment for hysol,  I'm not so sure.  This has been my business and livehood for about 33 years and never have had a question like this.  I think that if you rough sand paper the part you might have a better adhesion than with the Alodine.  It was designed for paint adhesion

Does  treating an aluminum part with alodine affect the ability of Hysol to stick to it?

 

As long as we’re on the topic, these (forward hinged) canopy hinge brackets look like they already have some sort of coating on them.  Did anybody else add some sort of protection to these things, or am I just overthinking this?
