Sound deadening on the cheap!

Due to having a MGB that I am restoring I go onto this forum on a regular basis; https://www.mgexp.com/forum/mgb-and-gt-forum.1/   There are regular discussions about both heat and sound insulation, the heat insulation is not really relevant but the sound proofing is. The camp is divided in two groups, one say's that Dynamat is the ultimate product and nothing can better it. The other group say that Dynamat is nothing special just clever marketing, they use other butyl rubber pads that are slightly thicker and a lot of others use bitumen based products like the Bostick one. Back in the day MG themselves used bitumen based pads, my GT has them on the door skins and they are still intact forty six years later. I personally think that the push to butyl rubber is due to environmental concerns rather than it being a superior product.
These are still available to dampen vibration and to level the floor in MGB's

Incidentally the product that I linked to is available in widths up to a metre wide

If you had a half decent heat gun you would find that you'd probably use it more often,
I last used mine to soften the mastic sealant that secures the water sheader plastic sheet behind the fuel tank panel, the old mastic had stuck to the sheet when I peeled away from the car, so all I had to do to reuse it was press it back with my thumb as I gently heated it....stuck back on like it had never been off!
Heat shrink tubing is your friend when working on automotive electrics, especially it you do it properly and use solder on your terminals instead of those worthless red blue and yellow crimp shit! A good heat gun is the best way to shrink the tubing gently. I eve use it to soften rubber hoses that I would otherwise struggle to fit over the barbed spigot

When softening hoses I usually stick the end to be connected in my wife’s brew whilst it’s still hot.
This is especially useful if it’s really cold, as I can be sure of at least one hot ear, possibly two if I’m not quick enough.
Whenever I’m doing any sort of electrical or electronic work, my heat gun shares the same importance as my soldering equipment.
It’s also great for blowing up the fire when the weather conditions aren’t favourable.
I don’t mind crimp connectors but with the proviso that they are of good quality & the correct tool is used. Cheap crimps create completely crappy connections. Correct?

Ok..ok..you are both ganging up on me...I may or may not invest in one but there is always just something else...
I solder a lot with guitar electronics and use heat shrink tubing..my soldering is good..just saying..wink.

C'mon you know we're right!
