Rattle can paint job on rim, will it survive?

[Bones]

^ Yep, those are the two I use.  I *think* that I improve the paint durability of small parts by baking them at 250F or so for awhile but can't prove it.  But regardless of the results it's  very  fulfilling to sneak bike parts into the kitchen oven.

LOL! yeah, my girlfriend was speechless when she saw my freshly-painted top triple baking in the oven!

[Norm]

I've done that too, but my wife was anything BUT speechless!!

Baking...how long after  you paint do you bake it?  and does that help it to just set better?

Thanks

not a good idea if you cook with that oven. those fumes are pretty nasty.

heating the item up will allow the paint to cure quicker.  especially since the metal underneath will heat up quick too.

About when to bake a part, I'm not sure I do it "right" but I wait until the paint is pretty much dry before sticking it in the oven.  I think the heat tends to polymerize the paint molecules (as if I knew what that means ) and make them tougher. 

No worries about fumes, if my wife comes home and doesn't ask "What have you been doing??!  What's that smell?!"  It's a safe bet there aren't any fumes.  More fumes  just living and breathing in NYC that baking parts in an oven.

Waiting is good...

it allows the solvents to evaporate so you don't get solvent popping.

The only way a paint can polymerize is chemically...

heat can only speed the reaction of what's already in the mix.

So, as far as improving durability, is baking paint a waste of time and energy?

Overall durability?

Yes.

Rattle can enamel takes a long time at room temp to fully dry so you are improving the initial durability by actually drying the paint.

I *think* dupli-color brand rattle can stuff is an air-dry urethane. No way it's even close to a proper automotive type finish for durability, but it is better than Krylon etc. for solvent resistance. Anyway, I painted the wheels on my '82 CB750F using  their "high performance wheel coating" 6 or 7 years ago and they are still holding up pretty good. Main thing is to get 'em clean before you spray.
