2 Questions RE: Bondo and Insulation Install

[Capebuild]

Hi.....

I've started gluing up the sidewall panels. The outside panel is adhered to the middle skeletonized panel with adhesive and crown staples. That outside panel will eventually get sheathed with aluminum sheet (which I intend to install using the "floating method". My question..... is it advisable to to fill the indents where the crown staples were shot through the outer exterior surface where the alum sheet will be mounted against with something like bondo? Fill the crown staple indents with Bondo?

2nd question: When I insert the foam panels for insulation in the spaces of the skeletonized middle section, they mostly stay in place via a fraction fit. There are some places where there's maybe a 1/16 to an 1/8th gap. Is it advisable to file those spaces with something like ProflexRV?

Thanks very much the help.

It would not hurt to fill the staple holes, but dont go to crazy trying to get them perfect.

as for the foam, just cut slivers of foam and wedge em in.

Thanks for the feedback, Scott.

I did go ahead and fill the staple indents.
Good suggestion on using the slivers of insulation. There's only 2 or 3 minor fill spots that need a little fill, but I like your suggestion.

Thanks!

Bondo is basically polyester resin & talc, so it will wick moisture out of the air if there's much humidity. Use something to seal the surface (a coat or two of urethane) prior to skinning so it's not pulling moisture into the Bondo under the aluminum.

Using rigid foam for a house, leave a 1/4" gap and seal with foam in a can. Airtight.
