frame painting question
I am going to paint a frame in order to cut down on the # of times I have to
remove the rust, the Acid Rain in my area is really bad on unpained steel. I don't really care about a hi-quality paint job now, I'll get it powder coated in 4 months anyway. Question = Should I use Spray or Brush on enamel and IS a base primer coat needed? I will be removing the rust and then running an Angle Grinder over the frame with a brass brush and add paint asap so I am not painting over rust. I am leaning more to cans of spray enamel...yes? |

There are some cool colors of spray paint that look similar to anodized metal. These allegedly don't require primer if applied on clean metal. (Duplicolor~ MetalCast)Its also not expensive. When you are finished with the wire brush, get some latex gloves and wear them while you handle the frame. Next get some lacquer thinner and a rag and wipe the entire frame with the stuff. Then you can hang the frame up by a couple of metal coathangers and spray it. With paint. Josh, please don't breathe or drink any of the stuff.

frame painting question
I was going to ask you 1st, but I cleared my address book to prevent any
virus attacks leaking out and I forgot to record your email on paper....and thanks for replying. Gotta get the trikes ready for winter driving really soon and the paint will help....I tried a thing called Krylon Spray Enamel on a delta and it peels off using your finger nail. Was thinking Tremclad 1st for the rust protector and then sumethin purdy on top. ******************** "rorschandt" wrote in message . 97.132...

Who was it that said Rust Never Dies? Classic car buffs tell me the best way to keep rust from returning is either sandblasting or immersion into a vat of some kind of rust hating acid. Specifically they tell me sanding doesn't cut it. Frankly the thought of having a frame with rust and a determined Joshua Goldberg with an angle grinder in the same room gives me a wee bit of concern. Here's my suggestion. Since you must wait four months to powder coat you should sand the frame, prime & paint with your spray cans, ride it until you are ready to powder coat, and then have the frame sandblasted or dipped immediately before powder coating. And don't forget to spray rust preventative inside the frame after powder coating. This, I believe, would give you a satisfactory long term result. skip |

yeah the place I will use dips the bike frame into a vat of something nasy,
blow dries the frame and does the sandblasting. Frames get 5 powder coats and a clear coat. In USD about $120.00 total, which I have been told is a really good price.. ************************* "skip" wrote in message ... "Joshua Goldberg" wrote in message .. .

A while back a friend took his frame to a local body shop, and picked a
color they had left over in stock. They sprayed and baked the frame, looks real great in metallic red. Total cost $75.00.

Joshua, That is an unbelievable price. 5 coats plus clear? In
Sacramento, CA that would be a great price for blasting and a single coat of a stock booring industrial color (no clear coat). Where do you live to get such great prices and have so much rust to worry about? Skip, It was Neil Young and the phrase was "Rust Never Sleeps". Don, (aging rocker).

frame painting question
I paint aircraft for a living, and I would do the following, if you can:
1. Wipe the whole frame down FIRST with Naphtha. I use this because it has enough solvent power to wipe off just about all contaminants and it is weak enough that it can't cause contamination/fish-eye problems later. For things like bug guts or tar, use a more powerful solvent, but then go back and re-wipe with naphtha. 2. Use as fine of a steel wire wheel instead of the brass one. The steel will lightly scuff the frame tubes and greatly improve paint adhesion and still not be so hard on the steel that the scuff marks will show through the paint. I use a small wire wheel with a ¼" shaft and put it in my electric drill. If you are planning to powder coat later, you DEFINITELY won't see the scratch marks later. 3. As for primer, if I'm going to use primer on steel, I use an epoxy (a base component and a catalyst/hardner component). Reason being, the epoxy primer is tougher and far more durable than any enamel or lacquer primer, especially red oxide (which I never use). The only problem with 2 part coatings, is you can't use a store-bought spray can. I have some small glass bottles that are screwed into a small aerosol container so you can custom make your own "spray cans" - but not sure of the name. Will get it tomorrow and post the name. If simple corrosion protection is the primary concern, don't even worry about primer. I am not a big fan of Krylon products, and for a straight store-bought spray paint, I have found the Tremclad brand to be every bit as durable and cheaper than some of the "dedicated" brands like Krylon. A light tack coat, then a couple good thick wet coats and you will have more than enough protection til you powder coat them. After shooting the paint job on my first two trikes, I took the last two I built to powder coat places and let them coat my frames in plastic. Very happy with the jobs and the powder coat is multitudes tougher than even the multiple coats of epoxy I put on them myself. The Mk I and Battleship were painted by me. The Mk III and IV were powder coated. Pics are he http://jkcc.com/speednviolence/bikes/ "Joshua Goldberg" wrote in message .. .

I've built a few trikes and know how it sometimes seems that all the planning breaks down to sticking things on because "Oops, I mis-measured" or "Hmmm, forgot about THAT thing!" I wish I had a locl powder coater that did frames that cheap. Here it is about U$130 - 200, with a very limited color choice. Happy trails, rorschandt http://pictures.care2.com/view/1/174801833 |
