Does this sound right? Paint question.

Framebuilders Thinking about a custom frame? Lugged vs Fillet Brazed. Different Frame materials? Newvex or Pacenti Lugs? why get a custom Road, Mountain, or Track Frame? Got a question about framebuilding? Lets discuss framebuilding at it's finest.

Does this sound right? Paint question.

Does this sound right? Paint question.

I stripped my bike down to the bare aluminum and have sanding away any remaining paint spots. With the right steps, good prep work and lots of patience I feel I can get good results. From the places i've called and the internet research I think I have my process nailed down. Does this sound right?

1. Clean the aluminum with some kind of metal cleaner
2. Apply alodine coating or another aluminum adhesion promoter.(haven't found this one yet)
3. Degrease the frame
4. Apply several light coats of a self-etching primer
5. Apply several light coats of a sandable primer
6. Wait about 24 hours
7. sand using 220-400 grit until smooth and any runs are out and tack clean
8. Apply my color layer (In this case Duplicolor Professional Acrylic Enamel) Use 4-5 light coats with about 30 min between each coat
9. Wait 5 days for the Enamel to cure and then wet sand using 1200 grit to remove any gloss so the clear will adhere well
10. Put any decals on
11. Spray Clear in 2-5 light coats (Duplicolor Professional Acrylic Enamel)
12. Wait until clear has cured and polish.

I'm using all Duplicolor so i'm not mixing brands at all. From what i've heard acrylic enamel is much more durable than laquer finish. Anyone in the know see anything wrong?

You don't need the sandable primer unless there are imperfections in the metal. The less layers the better as far as durability goes. Also understand that rattle can paint pretty much sucks and will chip and scratch easily. Sounds like a lot of work you are going though just to apply a mediocre finish on top.

Whats mediocre exactly? Is it just the durability of the enamel or the quality of the whole spray can concept?

Durability of the paint itself.

You don't need an etch primer either, if you're alodining the frame, either... :-)

Yea, i thought that same thing, but i'm having trouble finding an alodine coating in a small quantity. I think i'm just going self-etch primer and then spray color. If it holds up terrible, I can always just strip it again and go an alternate route.
