rust on muffler

[shotgun]

Is it normal for a two year old car to have rust on the underside of the muffler? the size is about 25 centavo coin. Can i claim it under warranty?

Yes, its normal. A rust spot isn't unusual. And nope, muffler is a wear & tear item.

IMHO, it's not really a problem you should be bothered with (unless it's already a hole that have rusted through). External rust isn't anywhere close to the corrosion you can find inside the muffler.

But if it really bothers you, just clean the area with a steel brush or rough grain sand paper and spray paint the area with high temp paint you can buy from the DIY store.

The undercoating material won't help much 'coz it will melt under the muffler heat. Spraying hi-temp paints will be better. Or replace it with a stainless muffler to save yourself from worries.

Undercoating will either melt or burn off once the exhaust system of your car gets hot enough.
