spray on sound deadening

[shadowm891 2]

hi everyone have a question. i just spent last weekend installing dynamate extreme in my 01 kia sportage to get rid of my rattles due to a small budget which made a big difference but i am still getting rattle in my doors and my hatch. and i was wondering if using some spray on sound deadening help even more.

Spray on deadener does not have enough mass to be effective.

i see what are other ways i could help stop these rattles then ?

It depends on what is rattling and why.

So, what is rattling and why is it rattling? We can't troubleshoot a problem if we don't know what the actual problem is.

the metal on my hatch and doors are still vibrating not real loud but you can still hear it outside.

then panels are resonating and flexing which will vibrate against other panels. which can be treated with cdl to some extent. as long as the noise is outside and not inside then who cares?
