Hey Goatherder, Ianf406 et al,

Based on your post, I was thinking of taking your advice and using the 3M ceramic micro-ballons, using the 610 grade due to the larger size. There are two applications I would need this for. One is the advertized advantage of using it for gloss control as I try to get the proper gloss for the semi-gloss black of the interior dash, sail pillars etc. (this is a '65 GTO and not a Jeep). More relevant for this post of course is the thermal and sound dampening properties. Regarding the latter, I was thinking of using some bedliner that I already have mixed with the micro-ballons. The bedliner is white if it matters, and I was thinking of coating the floors and ceiling with it underneath the carpet and padding. I would mix this with the ceramic beads and if proper, the normal air-filled micro-balloons as well. My question is whether I should use BOTH the ceramic AND the normal micro-ballons. My thinking is that this would be more ideal as the ceramic would insulate against heat and the air-filled would dampen sound. I supposed I would use one layer or more each, but I am really unsure if I should mix them together for each layer or use two different layers as I mentioned OR perhaps I would layer it and use 4 coatings interlaced. So for example layers as follows: normal beads, ceramic, normal beads, ceramic. Do you have any suggestions for this? I also was contemplating using memory foam for padding and/or aluminum sheets at least in the ceiling to reflect nose and perhaps add a layer of air between the ceiling surface and the aluminum sheets. Any suggestions from anyone would be helpful and thanks in advance!

 

I'd bet the directions on the product did too........................
