Re: Clear Coat Failure and Repair(with all pics)

timaishu:

If it were me I would deffinatley try it
1: you have a much smaller area
2: all you have to do us smoothe the edges of that spot and alittle around it to give the clear something to cling to.
Mine got bad because I was removing a defect that was causing the failure. Yours seems to be pretty straight forward.
Just be careful when sanding not to hit the base coat to much. Light pressure over that area so you don't go through it.
like I said with mine no risk here at this point it needs a repaint anyway so even if you mess up your posision hasn't really changed

I think I will attempt this one of these days.


So you chip off the loose clear, sand the edges and shoot it with clear.

Wet sand down the raised edge and compound it?

Yes try to get as much of the loose clear off as possible. The problem i had was trying to fill in where the clear had failed so as to have an even surface when i was finished. If you see it in person you can still see a slight out line of the defect. I don't think just taping around the affected area will work because i would think you want some overlap to protect the edges of the surrounding clear. Try to concentrate the spay to the exposed area and feather it out till you build it up. I've also heard that there is some painters tape out there that wont leave as much of a line this might be worth looking into as well.

Thanks Gary I had a video of me compounding the sanding marks but after all the issues i had with the original post i just wanted to get it done. I appreciate the time and effort you put into your videos. Informative and entertaining.

Thanks again for the compliment. You are the master of the review so that means a lot.

CEE DOG I got an email for your last post but for some reason it didn't show up in the thread you were talking about doing the work on a car and going through the base coat. Not sure what happened, but i definitely want to see how it turns out.:xyxthumbs:

Awesome job!! I thank you for the great write up. I have a friend with a green Corolla that has the same clear coat failure on the fender. It is just the clear flaking off no damage to the base. It looks like it was a repaint a while back and now the edges, starting from the hood, started peeling and flaking away.
I am worried about it being a darker color though, it may show up more. what do you think? If it shows a little on the silver color it would probably show more on a darker right?
 
Re: Clear Coat Failure and Repair(with all pics)

So I definitely want to try this. One of you guys mentioned using 2k clear.

Is this the stuff I should buy?

SprayMax 2K Urethane Aerosol Clear Coat

If Im going to do this I figure I should "do it right" the first time if this stuff is way better than the duplicolor clear.

Let me know you guys.

to be honest i think the only reason its visible is because i wasn't able to build up the area where the clear failed quite enough. so when i wet sanded, it didn't come perfectly even. i really think thats the key. once you do that it should hide the edge of the failed clear and blend pretty well.

with all the interest here i might just go out and test my theory out. though its hard to see and and hard to pick up with a camera i know its there and its starting to bug me. plus as i said in the beginning I'm not a pro painter so this is trial and error for me as well. what i can say is if you do everything that i did it will at least greatly improve the appearance. if you improve on what i did then ill be asking you for advice:D

That's probably the more permanent way to go. My only reservation would be that "Shiny Lil Detlr" said that once you mix the product in the can it has a pot life of 48 hours and i would imagine its a bit more costly. For as small as your repair is well lets say its something to think about. i don't know what the durability of the dupli color clear is. it was an automotive clear so it should have some durability. the can doesn't mention uv protection but i can't believe it has none. I'm definitely going to watch it and will keep the forum posted on durability.

just checked the link you posted and that product only lasts 24 hrs after activated. it seems to me you will have a lot of wasted product. the can i used was half that size and i still feels full. you just don't you that much doing these spot repairs. just my 2 cents. if you do try it we will at the very least now have a comparison test. :-)

And just to add, guys, you all hopefully do realize this is not a "proper" repair by any means. It's just a temporary fix even if you do go for a 2K clear. The only proper way to get a good permanent repair would be to clear the entire affected panel.
 
Re: Clear Coat Failure and Repair(with all pics)

I know. :(

I just dont want my fender to get any worse and I dont have enough money to get it repainted or re-cleared.

How long do you think this type of repair could last? Surely a few years right?

I agree with you ! I worry that the sandpaper was too fine of a sandpaper to adhere well and also the edges around the failing clear are going to show rings down the road .

Although I have to say it came outextreemly well its not how things are done. In a bodyshop the clear would be sanded off and primed and then sanded . It would then be sealed, then base coat and clear coated .

But it came out vey well and if your happy with it for however long it lasts then thats great .

I would not advise anyone to doing this on customers cars though.

I totally agree with you both. I hope this hasn't got lost in the mix so for others just jumping in here I will reiterate, Im not a pro painter. Im sure there were processes or techniques that were not done to the standard of a pro so i was hoping someone would chime in on that so thank you. this was a test repair that i was trying to see if it could be done with reasonably good results for my personal vehicle. with the economy the way it is we are all looking for ways to save money. i cant afford to have all that work done on my car so this was the next best thing till i can afford it. For sure and correct me if im wrong this will prevent it from getting any worse and will work better in my opinion than say opticoat or cquarts something that those products weren't designed to do anyway. i didnt mean for this to be the end all cure all for clear coat failure just a better interim repair. i hope it didnt come across that way.

Thanks for stating the whole process any idea how much it would cost to have a panel like this done? ballpark price?

That is correct, it should keep the problem from getting worse. The only potential problem is that since the materials used don't match what is on the rest of the panel, if you ever did go to have a pro do the work later on they might have to strip more off the surface than usual to prevent anything odd mapping through.

I'm going to guess anywhere from $300-500 to have it professionally repaired as long as the repair can be contained on just a single panel. If they need to blend the color onto adjacent panels either double or triple that estimate.

Re: Clear Coat Failure and Repair(with all pics)

Great work! You can't even tell in the last picture where the repair was done!
 
Re: Clear Coat Failure and Repair(with all pics)

Thank you for posting this. I joined this website specifically because of this thread. I bought an 11 year old bimmer that the previous owner let bake in the sun 24-7. The roof paint is oxidized, and a golf-ball sized section of clear has failed on the roof. Hopefully, using your technique, I can stave off having to have a repaint done, at least in the near future. Thanks again, great help!
