what to damp/deaden first

For those of you that have applied damping materials (RAAMat, SecondSkin, etc) and products like ensolite or mass loaded vinyl, can you offer advice on which product and how placed to return the greatest improvement?

I know I have enough (RAAMat & ensolite) for the two front doors then either the back panel (behind rear seats) or the rear doors. I want to get the maximum benefit in case I can't spread it out to do all three, hence my question. Or correct me if this isn't the three most important spots.

Later on (when the money tree sprouts new leaves) I might go to floor and/or roof, and whatever I didn't get to this time.

Oh, and I don't plan to use rear fill speakers (rear doors), just want a reasonably quiet cabin along with well treated front doors.

 

OK, not an overwhelming response. I guess most people do this all at once rather than incrementally.

So, based on what I read in several postings, notably Mr Marv's, and since I haven't yet selected speakers, I think I will apply RAAMat and ensolite to the rear cabin wall today.
