Does anyone have any idea as to why the paint on my truck is peeling, cracking, bubbling, and getting wrinkled like this?

It's a 1987 Toyota LandCruiser. The truck was completely painted just over 2 years ago and these bubbles and wrinkles first appeared about two months after it was painted. The pictures are as of today.

The truck was properly painted. it was wet-sanded down, bondo is small areas, cleaned and leveled, painted, primered, and baked. The car spent over a week in prep mode to ensure the bondo was dry, smooth, and leveled. The paint cracks in areas where bondo was used, and the rest of the car peels, bubbles, and wrinkles.
The wrinkles are found mainly on the hood and fenders; the bubbles appear mainly around the rear quarter panels in the truck's accent line or whatever it's called.

The truck is parked outside nearly all of the time and the temperature here is somewhat tropical (Addis Ababa, Ethiopia) Summer (November - April) temps are in the high 70's (20C) to low 90's (32C) but the sun rays are very strong due to the elevation (~7,700ft/2,300m) (cool mountain air and steady calm winds keep the temps down) and the rain season sees lots of rain with temps in the low to high 60's (15C)

Probably bad primer.

rust causes aerobic reaction and causes paint to bubble up. aka a really bad paint job.

In all honesty, it looks like I painted it.

The wrinkles is badly cured "flex" ( i'm guessing what you call bondo), that plus rust = bubbles.

Even if a tiny little speck of rust is left, that will be enough to ruin a good paint job.

Ambient temperatures have nothing to much if it's a bad paint job.

Cracks = bad flex and/or too much dilution, causes the "flex" to harden more, hence the cracks.

Paint wrinkles = bad paint job, bad temperature when drying.

In short, a hack paint job :/ you need another place.

Looks like a chemical reaction to the primer but you said it was an '87? Unless it's been re-sprayed recently I would guess the paint just hasn't aged too well going from hot to cold, cold to hot etc.

I would suggest you actually read the OP before replying.

Prep wasn't done right is usually why you see cracking like the third picture, for example I see the paint lines around the trim and that means if he didnt get it just perfect moisture can get under there and oxidize the coat from below.

Clear Coat failure on the spider web looking crack pictures, again, prep work.

Whoever did that paint job did a terrible job of it.

Thanks.

The work is still warrentied and still covered so I'm still able to recover the full amount.
I will need to find a better place and import better quality paint if I can't find it here.

Appreciate the feedback!
