If you live in a warm or hot environment another another product that is great but it is more pricey because you never a compressor and gun to apply is Lizardskin. They not only offer sound deadening but a thermal coating that can reduce the temperature of the interior by 30°. It also can be topcoated to color match your car color. This is the route I'm taking. They also sell angled wands that allow you to apply in blind corners. This might be a better option for a restoration or color change because of the amount of masking. Dynamat is more user friendly/easier to apply.
SXSMAN - I know this thread is a couple years old, but curious to know how your experience went with LizardSkin. My painter is recommending this stuff, he uses it on restorations all the time (everything from VWs to Ferraris). I live in Southern California where it's often 85+ degrees, so anything to reduce the heat along with the noise would be welcomed.
Plus, I understand you can spray it in all the hidden areas where dynomat would never fit, such as the crevices of the rear parcel bins, the roof under the headliner, and the inside/outside floors. Seems like it's well worth the additional cost, if it works as advertised.

I'd like to clarify. There is too much use of brand names and not product types. Hoodliner is different than butyl type deadener.

It takes about 150 - 200sq.ft. to cover all of the inside surfaces of a mini in whatever material you want. It doesn't sound like you'll be using a combination of materials, so I would recommend at a minimum covering the floor, the kick panels and front bulkhead/firewall behind the dash, the rear bulkhead behind the rear seat back, the roof under the headliner, and about 40% coverage on the doors/rear quarter panels
If you want a combination of materials, there is a much more detailed aproach depending on what noises you are trying to eliminate.
Do I recommend a hood/bonnet kit? 100% absolutely. At a minimum. 4 pieces of damping on the flat pieces between the cross brace.

Damping: (as in stopping something from vibrating) does not need huge areas, but only patches of material to stop a panel (door skin, roof etc.) from vibrating. Like a bell, the panels can generate their own noise.
Absorbing: there are two ways sound is absorbed- by heavy mass that absorbs sound from traveling through a panel, wall etc. - or by light "fluffy" material that absorbs airborne sound - fibrous insulation, upholstery, carpet, human bodies etc. (It works better if the bodies are clothed.)
Reflecting: physical barriers to reflect airborne sound (walls, glass etc.) You also have to block the holes, e.g the big one between the carb and the centre-mount instrument pod. The problem with reflecting is that it can keep sound IN as well, so you don't want much reflective interior surfaces. The aluminum foil backing MtyMous mentions works if it faces the sound source - you would put it on the engine side of the firewall. It would reflect some of the sound, absorb a bit (it is a 'soft' metal) and then the mass of black gooey stuff would absorb the sound that is transmitted and damp the car panel. Having the foil on the inside would be counter-productive as it would reflect internal sound back in and prevent the gooey stuff from absorbing it.

Sound deadening can be a complex process honestly. It all depends on what sound you want to isolate or eliminate. If it's road noise or engine/exhaust noise, the butly rubber and aluminum backing solution will only take care of so much. They are mostly for damping vibrations that resonate in the panels. That's a good chunk of the noise on a mini to be honest, but there are other things to consider.
Damping, Absorbing, and reflecting. Take care of those three things and you'll have a very quiet ride. Consider that most car noise is airborne or structural. Road noise is an example of both (resonance through suspension and into the body, and the sound of the tires hitting the pavement).
I think I did a post on here before about it, but I'll give you the quick and dirty.
Dynamat is great, but if you're going to compare it to other products just look at the specs. Thickness of the butyl rubber and thickness of the aluminum backing. The aluminum backing is part of the reflection, so thicker is better, but too thick and you can't manipulate it to contours. Thick butyl rubber is great, but the cheap stuff is REALLY messy to remove, and this is where the majority of your weight will come from. But as stated before, this stuff isn't made of lead. It's fine to coat the interior panels ESPECIALLY the floors and the roof.
I won't kill this thread with details, but there are entire forums dedicated to this topic. Bottom line is the quieter you want it, the heavier and more expensive it will be.
