mdwracer Posted August 10, 2019 Report Share Posted August 10, 2019 Anyone have pictures of how to install the fire block foam and make it look like a clean install? I am all about safety but also do not like the interior of our Miata (especially the rear package tray area which is very visible) to look horrible... Thanks , Mike W #172 OverUnder Miata Quote Link to comment Share on other sites More sharing options...

Thanks , Mike W #172 OverUnder Miata No pictures, but once that stuff is cured and has expanded way beyond where you want it, you can carve away the excess with a sharp knife. After that, it takes spray paint fairly well. Quote Link to comment Share on other sites More sharing options...
mdwracer Posted August 10, 2019 Author Report Share Posted August 10, 2019 I will pick a few areas to try and see how it goes... Am I correct in that the alumium foil tape is no longer accetable? Quote Link to comment Share on other sites More sharing options...
ETR Posted August 10, 2019 Report Share Posted August 10, 2019 A hacksaw blade in the hand does a good job trimming it as well. Quote Link to comment Share on other sites More sharing options...

I can confirm that is no longer the case. Quote Link to comment Share on other sites More sharing options...

Am I correct in that the alumium foil tape is no longer accetable? You are correct. What they would like to see now is metal covering every opening / gap in the factory package tray. Ours is completely covered with aluminum, then we used fire foam to fill the very small openings where the roll cage back stays go through it, as well as any other place we felt would be beneficial. Like enginerd said, it expands WAY beyond where you want it so in no way does our car have giant openings being filled like it looks. We ran a bead along all the seams where it meets the back stays and the chassis. We raced it like this at Daytona and none of us even noticed the orange while driving. If you want more pictures I can get some tomorrow with the roof off it it'll help you. 2 Quote Link to comment Share on other sites More sharing options...

Also keep in mind that there is fire block sealant available that will seal small gaps and not expand through the panel to the other side. Might be a more suitable product for sealing bulkheads and places where panels are touching, and save the expanding foam for gaps you can't get to reasonably but still want to keep buttoned up. https://www.amazon.com/3M-CP-25WB-10-1-Barrier-Sealant/dp/B00176M30Q Amazon even sells it in a 5 gal bucket for some reason. 1 Quote Link to comment Share on other sites More sharing options...

Some of that is "drying" type that looks like mortar when dried. I used that by accident once. Flaked off. The flexible version i have heard stays pliable. 1 Quote Link to comment Share on other sites More sharing options...
TimS Posted August 21, 2019 Report Share Posted August 21, 2019 Hilti make some better products. This is kind of like bathroom caulk. They also make a play do type version. https://www.ebay.com/p/Hilti-CP-606-Flexible-Firestop-Sealant-Red-209634-19-6-FL-Oz/1700136706?iid=122383186422&chn=ps&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&itemid=122383186422&targetid=595232442869&device=m&mktype=pla&googleloc=9009905&poi=&campaignid=2086169719&mkgroupid=76147899806&rlsatarget=pla-595232442869&abcId=1141016&merchantid=113520858&gclid=CjwKCAjw1_PqBRBIEiwA71rmtQMQfszCLJh_cOWyqQeMyyzRsmBqe1_sDsXwdxyFjFjrP5lulrmJZxoCPIsQAvD_BwE Quote Link to comment Share on other sites More sharing options...
333 Kinkle Posted August 22, 2019 Report Share Posted August 22, 2019 Same as above. I used red 3M fire foam from Home Depot. Cut it later with a box knife and looks okay. Quote Link to comment Share on other sites More sharing options...
