Underbelly insulation repair after blow out

[Cyguy8]

Hello all. I had a blow out and it shedded the insulation behind the tire on my underbody.

I am writing to ask if I need to buy the same insulation that I have for the rest of the underbelly or can I just use spray foam insulation for the repair?

Taking it to an Rv Repair shop for them to do my new drum brake installation and was going to have them take a look to ensure there is no structural damage then depending on the cost I might have them do the insulation repair or I can buy a can of spray foam which I’ve used in the past for smaller holes.

Spray foam may make any future inspection or repairs more difficult.

As many know I am not a fan of the underbelly being covered so I personally would have removed it.
