I'm in the process of installing the stainless steel firewall, should I seal the edge and if yes what do I use? 

  

Thanks

 I assume that you put the fiberfrax between the plywood and the SS sheet.  One thing that I did that I am very happy with is to put a large metal washer at  each point where something is attached to the firewall, with a cutout of the  fiberfrax around the washer to prevent the compression and buckling of the SS  sheet when the items are tightened down. A high temp (red) RTV could work to  seal the edges.

Hi Mike,



Before you install the stainless steel you may also want to paint the firewall with intumescent paint.  You can buy this type of fireproof paint on ebay and many places online.  You may also want to paint the inside of your cowling with this paint.



You can use DAP Firestop silicone to seal any firewall penetrations and the edge of the stainless.  You should be able to get this at Lowes or Homedepot. I assume you are using fiberfrax or similar behind the stainless.

 Hi All

I did exactly the same thing.  Large area washers behind the big bolts and normal washers behind the small bots.  I bonded the washers on with the fiberfrax adhesive and I have 4 ply pads on the front of the firewall in the engine mount attach areas.

If I did it again I would make very large washers, maybe 2" in diameter, to use under the engine mount attach bolts.   

I used red RTV around the edge of the firewall.  

I also plan to coat the inside of my cowl with this...

http://www.homedepot.com/p/ForceField-FireGuard-E-84-5-gal-Intumescent-Primer-FFGD-E84-g05/203582028?cm_mmc=shopping-_-googleads-_-pla-_-203582028&ci_sku=203582028&ci_gpa=pla&ci_src=17588969&gclid=CKmZ5srE2coCFUOVfgod4nkGtQ&gclsrc=aw.ds

It is a primer coat, but it expands when exposed to flame to form a thick insulation.   There are some very impressive videos on you tube.  I would also put a couple coats on the firewall and maybe on the underside of the forward fuselage where the cooling air comes out.
