View Full Version : DuPont URO Question
06-14-2006, 12:13 PM
The sheet on URO says it may be applied to "properly treated" metal. Can someone elaborate on what exactly they mean by this. I want to overcoat Glasurit Epoxy and there are some minor sand throughs that I will treat with Picklex 20. Do I need to reshoot epoxy, or can I proceed directly to the URO Primer Surfacer?
"Properly treated" for production shop purposes generally would mean over etch primer. Uro is not recommended to be used on bare metal. It could be used over epoxy primer also, but I'm not a fan of epoxy primer.

Why don't you like epoxy?
If I read "apply over properly treated metal" I would NOT think it meant over etch primer. To me properly treated metal is clean and scuffed metal with no rust. I use Glasurit epoxy primer a lot and find to work quite well but I know nothing about Uro Primer Surfacer.

I would have to agree with Len on that definition of "properly treated metal"
That is metal that has been cleaned, abraded for adhesion (chemical or mechanical) and treated for rust.
I assume we are talking URO 1120S/1140S Primer-Filler as it's the only one which lists metal as a substrate.
URO 1101S/1104S/1107S which can be mixed as a Sealer or Filler only list's metal as a substrate for cut-throughs and then only when mixed as a Filler.
In the end I don't see why you couldn't just do as your intending w/the Picklex.

I thought "properly treated" meant nice comfy A/C, some soothing Barry White, and a nice Chiante perhaps:cool:
My NASON spec sheets said properly treated means using Etch primer or other chemical treatment to prevent rust.
