Painting UCAs...

[Lighthorseman]

Just a quick question...I suspect it's been posted before, so my apologies.  I did a quick search and couldn't find anything.

I have removed my UCAs from my 70 Satty, removed the bushings and the balljoints.  I have given the whole thing a very comprehensive cleaning with a wire brush.  The UCAs are very clean - nice and shiny, actually.  My plan is to give them a final cleaning with acetone, then paint them with POR 15's satin black. 

My question...will the acetone be enough of a base clean, considering that they're already very clean?  Should i perhaps be using some sort of etch orsomething to make sure the POR 15 sticks properly?

Thanks in advance for any input!

If they are bare steel, I believe they need to be etched for POR paint.

I do use an etching type primer over bare metal. Even the spray can stuff is better than nothing.

Thanks guys!  I wasn't sure...but had my suspicions. 

Always better to do it properly the first time.

Doesn't POR15 want bare metal?

Actually no.  POR is for Paint-Over-Rust.   So if you want to use it on NEW metal you should really rough up the metal or chemically etch it.  I would think that's true of any coating onto bare metal, POR primer, etc.  If fact POR makes a product called Metal Prep (I think) that they recommend you use on bare metal before you use POR paint.  It's an etching metal treatment.

Yes...I checked.  I'm going to use POR 15's metal prep, then paint.  I plan to do all the suspension bits, and I'd rather only do it once, so I want to do it properly the first time.

Thanks everyone!
