I'm considering getting an old titanium frame painted. Just wondering how much does the primer, paint, and clearcoat - all of that - how much weight does it add? And are there any issues with painting titanium. I heard of problems with getting the paint to adhere. Is this really an issue if I decide to go with a professional frame painter?

Mercedes race cars in a race sometime during the 50's was a bit overweight, so they stripped all the paint off the cars to save weight. That is why Mercedes official car color is gray/silver, the color of an unpainted car. But on a bike, the weight of paint is negligible.

Don't forget that when paint dries/cures, the heavy part is the paint, the suspension agent (liquid) evaporates, so the only thing left is dry paint, very low weight.

I have heard that on a Boeing 747 the difference in weight of the plane if all parts are painted to the min. paint thickness vs the max. paint thickness is about 4,000 lbs. So on your bike it would be about 2 ounces. I guess it all depends on what you can live with.

WHY would anyone paint a Ti bike???:twitchy:

Ti is the only material in which surface blemishes can be removed in one minute with a ScotchBrite pad.

(And this is coming from a guy with a painted Litespeed.
I bought the frame off eBay and love it, but would like to strangle the fool who ordered it new.)

Stripped my bike today and gregam is correct, almost exactly 2 oz of paint came off my bike. 54cm.

Don't forget the stainless steels (953 and XCr).
