Yaris Sedan Deadening and Sound system upgrade

[swidd]

I did the undercoating way back before much else, and did not notice much improvement if any.

It did make the wheel wells look better though. All black and deep, hiding the cheap plastic and thin metal... But it wears off after a while.

go with Duplicolor brand... better quality. Mine is still going strong after 45,000 miles & 2.25years. I've spent probably 1,000 of those miles on dirt/gravel roads too.

if you want both looks & sound improvements... you gotta go with one of the paint on/spray on sound deadeners that comes in 5 gallon buckets for example the second skin spectrum. Everything else either won't put on enough mass, or doesn't cure hard enough.

With the duplicor brand spray can stuff (I think $8 a can) I only notice a reduction when comparing a rock flying off my tire into the wheel well at highway speeds... I notice it is slightly muffled compared to when the well was naked (pre-coating).
