In all the reading I've done, I think that is a minority opinion with little to back it up. But that's not the purpose of this thread.

BikeManDan...neat picture.

I did some internet research on this subject, and it turns out that C'dale welds practically come out that way...they double weld, with the second pass laying down more metal. The few bumps that are left are sanded off, but according to the reading I did those are actually very few, and the double pass achieves higher weld penetration.

I don't weld, but it sounds plausible to me.

So. I'm not going to touch the welds on my bike. I intend to Bondo over them, and then powdercoat. Who present knows a powdercoat safe/compatible Bondo?
