I've read a bit about sound deadening and one technique is to fill hollow spaces with expanding foam to kill resonance. I was thinking of doing this to my roll bar top and maybe the sides. Knocking on the top shows how high of resonance it has. I was think that if I drilled some hols 8-10 inches apart on the underside of the roll bar and sprayed in the foam I could kill the resonance and just fill in the holes. I'm not sure I could weld them since the foam is in there, but maybe solder or lead them in, or maybe just bondo?
What's your reaction to this? Good or bad idea? |

Jeroen is right about the expansion and I have to say here that it may not be very wise to use any spray-foam or other 1 component foam. The volume of the targa bar is so big and there are too few and too small holes to outside, that it will take a long time until the foam is cured. I think you should use 2 component foam that cured chemically, not by air-drieing.
