Firewall Sealant for RV-12
I tried to get the MC-CS-1900 Firewall Sealant and Vans said they weren't allowed to ship the stuff in the mail and I don't know where I'm supposed to get it. Does anyone have any ideas?
thanks
Meade and George

I called to order the sealant a couple of days ago and got the same answer. I couldn't find it around her locally, so VANS just said to use something like Permatex high temp gasket sealer. Steve

If you are talking about the seams between the three firewall panels as described in the construction manual , you do not want the firewall sealant.
It is very thick, intended only for sealing and fire proofing wire penetrations etc.
The best choice from Van's would be the small (1 oz?) fuel tank sealant kit.
Note...do not use silicone based gasket sealer anywhere you are going to paint (such as sealing the interior perimeter of the firewall) If/when you paint the cockpit interior, paint will not stick to the silicone sealant.

I don't think Aircraft Spruce carries anything other than the Permatex.

RV 12 Firewall Sealant
I called Vans back and Scott said he had checked with the tech guys and they said in order to keep E-LSA specs, not to use the Permatex. I was given a number to call and they are sending me firewall sealant to use on the RV12. If it works out ok, they want me to forward their phone number to everyone.
I just checked and a guy named Ralph Roppo at PPG has a sealant SP 700 which should fill the bill. His cell number is 206-450-0849 and he welcomes inquiries.

Meade,
Please clarify. Was the SP700 sealant, that you are procurring approved by Van's in place of the MC-CS-1900 Firewall Sealant?
Which brings up a question. When deviating from the plans, do we need a document from Van's that approves the deviation?

Sealant approval
I spoke with "one of the Scotts" at Vans and he recommended PPG to me for a source for firewall sealant. I just assumed that it was ok to use the sealant. the guy at PPG was really great to work with.

Fuel tank sealant is not good for the firewall because it burns
