Hello everyone

Just starting to build again and some of my edges that have been in storage have started to show some signs of corrosion - small light oxidation patches.

There is a grey top coat on the edges.

Normally I just slap them straight in, not polishing, blasting or anything. So far I haven't had any delams etc

However and as with all things there is aright way and wrong way.

Would anyone care to enlighten me?

Thanks

You want to sand off the oxidation. The edges I've been getting are already prepped (ie sandblasted). I normally will wipe them down with a dry cloth to remove any dust, etc that may have collected from the shop.

Not sure what you mean by a "grey top coat". That grey color is probably from the sand blasting done at the factory. The edges will be bright/shiny after a base grind and edge sharpening.

I understand that they grey film is a bonding agent that helps the adhesion of epoxy to the steel. Like a primer coat. I'm not sure if this makes for a better bond than sanded or sandblasted steel, but perhaps it prevents oxidation prior to laminating the edges in a board. I have always just laminated the edges with the frosty grey coat on them and I am not having delam issues.

I usually wear cotton or other light gloves when working with edges and base material. I think the worst thing you can have on them is either a little rust or oils from your hands that might repel epoxy to some degree. I have a small bundle of edges with varying degrees of rust that I'll probably never use, too much work for an edge worth a few bucks.

Yes its a primer coat they apply and it also prevents against rust. If theres no rust just wipe down with a light solvent and go.

Lightly remove surface rust with a new clean scotch brite or fine grit sand paper. Try to leave the primer on.

Wipe down with a solvent like acetone to remove dirt/oil.

Be sure to remove any CA glue that gets on your edge bonding surface prior to layup.

Thanks folks - I will do as directed

Also you can use some king of polishing attachment on a drill

It removes rust saving primer.
