Title: primer Post by: Tom W2ILA on February 28, 2005, 02:40:47 PM On aluminum military rigs some used no primer, or yellow zinchromate primer or green zinchromate primer.
These primers are becoming hard to source but I have found West Marine still has zinchromate in green and yellow. The brand is "Tempo Marine Outboard Stern drive Paint". It was stocked in the outdrive section not the paint section of the store. TM Title: primer Post by: WA1GFZ on February 28, 2005, 03:11:44 PM I've seen it in a local Star Hardware.
Title: primer Post by: W1RKW on February 28, 2005, 03:24:15 PM I've used paints particularly the rust preventer paint called POR-15 from this place at http://www.por15.com for the underbodies of previous cars. It does what they claim. It's tough stuff. It's moisture cured unlike common commercial paints and coatings that dry by evaporation. Warning: Don't get it on your skin. It'll never come off.

Title: primer Post by: WA1GFZ on February 28, 2005, 03:30:07 PM I've used por 15 and navel jelley. I also found some good stuff in a spray can at home depot. I think these are for steel only.
Check out a good boat place. There are a couple good ones in Niantic for paint. I also found the price of stainless hardware quite good. Title: primer Post by: W1RKW on February 28, 2005, 04:02:20 PM Por 15 can be used on aluminum and just about any other metal too as far as I know.

These things were made in huge quantities to be shot out of the air by the enemy. The paint only had to last a few months... and zinc chromate would add more weight, build time, and expense. 73 John Title: Primer Post by: Tom W2ILA on February 28, 2005, 07:23:20 PM Yup, AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
Scabby because of the paint system and scabby because it was treated like a rental car throughout its lifetime. Strange that some gear got really good paint. The amphibious trucks got real coatings of zinc chromate before the OD. That way they had a real sacrificial coating over the steel or aluminum. The plan was to make the thing look good even though it was going to get blown up pretty quickly. There are still a ton of WWII jeeps around because they applied a pretty good coat system of read lead primer and OD. The electronics was a different story. Aircraft often has no primer under wrinkle black. But the BC474 and BC654 had really nice paint that has held up. There are a few BC610's out there that still look mintola. |
