Passed my burn test. 3.3 inch/min which is well below the 20 inch/min required. 2020 11 30 TR2620.1.pdf

Okay, I've relented and sent off my foam samples to Aeroblaze with a check for $75. I ticked the box for the 20 inch/min horizontal test. This matches the AC 23-2A description for the CAR 3.388 flash resistant materials. I guess that I need to add a NO SMOKING placard, as well. Thank you folks for the education.

Okay. So now I'm curious. Is my 1976 Mooney 20F certified to CAR-3 or part 23?

Didn’t worry about that.

It's just regular foam. This shop specialized in automotive seats, so the foam is a little denser than what is used for furniture. It was $300 for the two bottom seats. The seat back foam was fine. Used four new 1/8x1" cotter pins for the track stops. I collected these from my mechanic rather than pay $10 for shipping from Spruce.

Laughing! The image rotations on my phone would not upload. Thanks for the help.

I read previously that folks are concerned with moisture and corrosive combustion products. At this point, I'm sold on the Reiff preheat system.

Had a local upholstery shop replace my front seat foam. No before photo, since they look the same. They sure feel nicer, and no more foam crumbs on the floor.

With my 500w inverter, I can only push a maximum of 100W into the heat gun. The exhaust temperature is 62 C on a 24 C day. I'm thinking this is reasonably safe to try; although it may take way too long.

I agree. My plan is to rest the heat gun on top of the engine making sure the exit temp is safe. Then install the cowl plugs and leave it to warm the engine. My inverter only supports 500w, so that's the most I'll be able to pump into the engine compartment. I'll give it a try and see if it works.

Thank you for the good advice. I'm planning on dialing it back to keep the output temp safe.

Agreed. I'll probably end up there. Do you know the total watts for 4 cylinders and the oil pan heater?

Great! I selected this gun since my inverter can only handle 500W. I'm planning to dial back the heat until the inverter is stable.

Has anyone had luck with using a heat gun to preheat you engine in the winter. I've seen many clever solutions posted. I'm looking for something cheap and simple. https://www.amazon.com/dp/B07FM974CY/ref=cm_sw_em_r_mt_dp_Q7bPFbZF24P1K?_encoding=UTF8&psc=1

Finished the installation. Added large washers to prevent the arms from catching on the trim. Rosen provided a replacement screw. Cleared the threads with a tapered rap.
