Heard recently about a Cirrus that was repainted and was for sale. Failed prepurchase inspection due to paint being too thick.

Never heard of this.

Thick paint somehow overinsulate the composite structure leading to failure in the heat?

Lightening strike requirements?

When I repainted my grumman, my mechanic ended up doing a complete weight and balance, had to remove the elevators to weight them separately... It was a big deal. Ended up costing me quite a bit for that annual.
If you think about it, paint is heavy, so yes, it makes sense. Specially aviation paint, that is actually more like an epoxy that cures, so the weight remains. If you use 5 gallons of paint, guess what, that is close to 30 lbs extra of static weight, in weird places that could change the CG. So yes, it is important. And we know how fussy those clown planes are with stalls and spins.

Or the wrong color. Dark colors, even darker whites, can overheat the composites.

It very well could be due to lightning strike requirements. Too much paint over a conductive layer (I'm not sure what they use) prevents the strike from flowing quickly enough to prevent structural damage. Paint is resistive...which is bad in this instance! If the strike lingers it will blow right through the composite structure. That is especially frightening with a fuel tank in between...

Maybe it was just too heavy. The Cirri don't have much in the way of useful load as it is. Since you can't really "fail" a pre-buy, it only means that the buyer declined to purchase. There could be a million reasons.

It may not have been that the paint was too thick but that the wrong paint was used. My understanding is that only certain paints are allowed to be used on the Cirrus.

Cirrus is faster than lightning.

Bryan, Bryan, Bryan,

You know why it "failed" ( I have seen your videos) there was no red carpet and 2 water bottles there. :lol:

Don't own a cirrus and probably never will. Nevertheless, I am curious how one preps a composite airplane like a cirrus or many of the other composite airplane for paint? I imagine stripper would be a bad idea. I would guess just sand back to primer by hand? An orbital sander may get to aggressive and get go through the paint into the composite. Sounds like a lot of work.

Greg Mink has a good video with the shop who painted his (composite) Premier. Explains some of the differences.

Whoa! is this THE Bill bennett? From the Socata Bill Bennetts?
If so, Hey! Small world.

If not, disregard all that.

I still see your Trinidad at KDTO from time to time.
We upgraded (sold our souls?) to the Cirrus world when we outgrew the TB9.
I recently picked up a Grumman Traveler. It s slow but beautiful. When something is that pretty, you don't want it whizzing by at a high rate of speed, you want people to be able to admire it... For a long time... in a single pass.

At anyrate, I hope all is well.
If you are ever looking to fly somewhere for a bite, give me a holler.

Cirrus has special paint requirements, can't get a normal paint job.

How does one ascertain paint thickness? What is the specification?

Sure Flight is next door to us.
Great facility.
