kgreen Posted August 12, 2020 Share Posted August 12, 2020 Has anyone found a source for the old asphaltic based insulation used on GM cars in the late 30]s to 40's? It has a pressed pattern on it that looks sort of lie expanded metal grate. Link to comment Share on other sites More sharing options...
8E45E Posted August 12, 2020 Share Posted August 12, 2020 I would use truck box liner, which can usually be mixed to the same consistency of the original asphaltic undercoating. I prefer it as it will always keep its 'like new' jet black look, versus asphalt which picks up dust and dirt, and looks 'old' after a year or two.

kgreen Posted August 12, 2020 Author Share Posted August 12, 2020 Thanks Craig, I will be able to use readily available modern material in hidden locations, but I need to reline the bottom of my trunk lid. This insulation is quite visible when the deck lid is open so I want to be as authentic as possible. Link to comment Share on other sites More sharing options...

Yes, on the underside of the trunklid, well away from direct exposure to any road dust and grime, etc., the original should still look good after several years. One my one car, the only place I'll leave original is the underside of the trunklid: https://forum.studebakerdriversclub.com/forum/your-studebaker-forum/general-studebaker-specific-discussion/47592-let-s-see-those-66s Craig Link to comment Share on other sites More sharing options...

46 woodie Posted August 12, 2020 Share Posted August 12, 2020 What got my attention in your post, is the mention of a pressed in pattern that looks like an "expanded aluminum grate". I have been using a sound deadener made by 3M, part number 08840 that has such a pattern. Might be what you are looking for. 1 Link to comment Share on other sites More sharing options...
John_Mereness Posted August 12, 2020 Share Posted August 12, 2020 It is made/reproduced - I bought it for the 1939 LaSalle 3 years ago when doing restoration (needed for a 100 point restoration) - I think I bought it from a Ford supplier. 1 Link to comment Share on other sites More sharing options...

JACK M Posted August 12, 2020 Share Posted August 12, 2020 If you are doing a trunk like the one in your link I am curious how you would get it in there. Link to comment Share on other sites More sharing options...

The stuff from Ford is a square checker pattern. Link to comment Share on other sites More sharing options...
Akstraw Posted August 17, 2020 Share Posted August 17, 2020 Not sure exactly what you are after, but I bought something like this a year ago from a company called California Pontiac Restoration. Similar to this current listing on eBay. https://www.ebay.com/itm/WAFFLED-UNIVERSAL-HOOD-DECK-LID-INSULATION-PAD-MATERIAL/303561440996?hash=item46adabfee4:g:--EAAMXQwKdRffJo Link to comment Share on other sites More sharing options...

I was told by a body man that he would need to take the trunk skin off of the trunk frame, apply the deadener/insulation mat to skin and weld it back together.

Dan O Posted August 19, 2020 Share Posted August 19, 2020 Also, you can find that patterened insulation or something that looks close above the headliner, fixed lightly to the roof, in 1949 Roadmasters. Might look in a parts car but it may be crispy by now. I have it in mine but have not had a chance to compare closely to what's in the trunk.
