Use dynamat (or Damplifier,) then second skin spectrum, this can then be sprayed over to match bodycolour. Looks pretty factory too (in a dimpled way
)
Can you be a bit more specific dyanmat I have heard of but what the hell is second skin spectrum... etc?
No problem.
Ok, damplifier is a soundeadening mat, which is very similar to dynamat. it is metal backed and should really be rollered into place. this matting is great, but does not look very '914' So the next trick is to add 'spectrum' on top...It is a thin paste which can be sprayed, rollered or painted onto any metal surface.It was designed as a vibration/panel damper, but it also contains anti rusting compounds, so is ideal for painting on inner surfaces.
It can be painted straight over the matting, and ideally in a 2-3mm layer.. A thickening agent can be added to it to really thicken it up into a goo - but this is best left to the car audio guys..
Here is an image of damplifier covered in a layer of raw Spectrum. in this image it has dried to a grey, later (current) batches have a black dye in, which imo looks better. It can be sprayed or painted easily in a colour of your choice.
So there you go, I have used this in the past to great effect, and when I rip out my 1.7 and replace with a 2270, thats what i'll be doing to my engine bay
