Painting over anodize?

Gone Fishin' · 2009-08-30T08:01:39+00:00

Is any special preparation require when painting over a newly oxidized steel surface? Will either fine roughing up with 400 grit work, or using a regular oxide primer? Or...?Thanks.

I've taken about four of them over my life, starting in 5th grade and ending with an employment test around six or seven years ago. Mine were remarkably consistent. I thought the last one would show evidence of decline, but it actually was the highest.

Ah, well, we'll never match Gunner. I hear he tested at 157. Or maybe he said 154. He probably turned down his invitations to the Glia Society and Iquadrivium. They were beneath him. d8-)

I'll be sure to look into it if I ever spray two-part polyurethane. I was discouraged by the air systems they recommend. More junk in the shop, and a lot of money.

Regarding your reaction to epoxy, do you remember if it was always that way, or if the problem built up over years of exposure? You can get an accumulative reaction to epoxy to the point where you can't touch CURED epoxy without developing a rash.

At one time I used quite a lot of it, and it always worried me. I was always careful with the stuff when laminating with it, using respirators and gloves, etc.

P.S: Why are "heavy duty" batteries the absolute worst on the market?

Candy Apple Red Metallic would look good on my server rack, with the custom built eggshell white server cases. :)

They are 'heavy Duty' Carbon Zinc, AKA 'flashlight' batteries'. They are exactly what you want to buy when you need heavy duty crap.

You mean that there really *is* still a source for zinc-carbon D cells? I've wanted them as sources of carbon rods from time to time.

Enjoy, DoN.

DoN, if you are looking for graphite rods, I can send you a few from my stock. A bit larger than the ones from D-cells, these are about 5" long and 1" dia. Contact me privately if you're interested.

Best -- Terry

Thanks -- but those are a bit large for the purpose, so I'll skip them. (And since we are not organizing a transfer of things, I'll stick it here so you know that I've seen it, and others know that I have responded.

Thanks, much, DoN.

Have you checked with the local welding supplies store? My office opens onto a fab shop, and they use carbon electrodes in their "air arc". They strike an arc and blow compressed air through it. I think it might be called "gouging". It blows away a LOT more metal than OA cutting does.

Good Luck! Rich

Thanks -- next time I need them I'll check there. Since I don't (yet) have welding equipment (other than a bandsaw blade welder) I don't get to the welding supply place very often.

Thanks again, DoN.
