Clear coat blistering on roof

The clear coat on the roof of my light blue Yaris is blistering. It is about 9 years old.

Is this problem very common? Is there anything I can or should do?

Thanks,

R.

peeling clearcoat Yaris Red Blue

join the club. when, say hanging about the car chatting w/ a friend, scratch off the loose edges. (on my red hatch's hatch, they're cup shaped and the dew fills them w/ dirt.)
my interest is finding a way to remove the clear coat without removing the base coat. Then using what is best for a one shot red respray...no reason for fine finish. Just want non-distracting protection. The peeling sunburn look really stands out, and varies wiith the weather and lighting.

I got a 2015. I did notice the paint isn't the thickest out there. Seems a bit cheap.

I wonder if an application of a paint sealant like this would ward off what you guys are getting.

Yaris clearcoat removal save base coat.

Thanks for the search. I read all the posts, but didn't watch the youtubes. Anyone: If you ever encounter a tip on just removing the remaining clearcoat layer without hurting the base or primer (if there is a primer layer), kindly pass it along as a post on one of these Yaris clearcoat threads.
I don't care much about the peeling sunburn look, but want to protect the base coat and don't want to strip down to metal. Problem w/ scratching off the loose edges of the clear and then rattle-can shooting the large base-exposed areas is that the new paint over progressively releasing remaining clearcoat would create another type of flaking problem to deal with--maybe stiffer red-over-clear flakes that might curl and bubble but not want to break off.
(Guessing clearcoat problem may originate w/ solvent -free water-base paint chemistries used for environmental reasons?)

You can sand gently with an electric sander. I would use 600 grit and keep the sander moving. If you sand too aggressive you will see the primer underneath. I would recommend using 3M sandpaper.

Get the surface of the roof as uniform as possible, The flakes are high spots
Another words you need to make those flakes blend in or disappear in the surface of the roof.

Once you have the roof scuffed up you can wipe down with acetone and a lint free rag. After that you wipe down with a cheesecloth. Thats a tacky rag that will pick up particulate. Do not touch surface with bare hands. The oil from your skin will contaminate the surface. Mask out the rest of the car. You can use newspaper. I recommend shooting the base color of the vehicle with no clear coat. That means you will be shooting the paint and no clear coat.

The color of the paint is determined by the paint code which should be located I think on the drivers side door. Check with Toyota if needed. Go to a reputable automotive paint store and tell them the color code and manufacturer of the vehicle and they will mix the paint for you. I recommend using Nason. It's an affordable Dupont product at the fraction of the cost. Shoot inside if possible and if its below 50 degrees you will need reducer which is paint thinner to get the paint through the gun. However if you are 70 degrees or above you will need a minimal amount of reducer to get the paint through the gun.

You can buy a cheap Husky gun at home depot for 29 dollars and it will get the job done. You can buy your acetone at home depot too. DO NOT USE PAINT THINNER FROM HOME DEPOT. You must use automotive reducer.

Do multiple thin coats and wait 15 -20 minutes between coats. Try not to exceed 2 coats.By shooting the base color without the clear it will match the color of the car perfect without any reoccurring issues of clear peeling.

You can use a 2 gallon compressor to do the job. Have fun and remember to wear a good breather.Use 3M and the 3M filters for your breathing protection. Most important.
Have fun and enjoy your new finish
