...to get an answer, or at least an explanation about this two issues..:



I see lots of threads on fixing paint, some diagrams show paint over primer and how if you fill the scratch with paint and wet sand and buff ...done deal...



Medium%20Scratch.jpg




I don't see the clear coat on the surface on the picture which leads me to ask ...where is it??..



So now based on this...I can fill a scratch, wet sand and polish/ wax and I'm back with a shiny finish...temporarily or until the next wash?



question 2:



After I wash the car and clay it later on...do this flaws re-appear or does polishing the clear coat take care of the problem for good, meaning am I just covering up the flaws or am I fixing them for good??...

Wet sanding clear coats???



Sorry if I have missed some threads that may have explained these issues but...I hope someone can answer them right out.







Thanks.. :wavey
 
That's a big "depends".



If the paint is exactly like that diagram suggests, then it's just a single-stage paint job that doesn't even have a clear, so essentially, it's just that - touch up and do whatever to make it look like new - wetsand, polish, etc.



On a clear coat, it depends. If you have a scratch that goes THROUGH the clear like a rock chip might, it's very much the same process (although you may want to clear over where you touched up the spot).



When you say "flaw"... if you've touched up a scratch, then it's touched up and you'd have to scratch it again to make it "reappear". On the other hand, if you were talking about swirls, then you'd have to make sure that whenever you polish that panel, that the polish is REMOVING the swirls as opposed to just hiding them like #9 or SMR might do.



Not sure if that answers your question or not...
 
Polaris, thanks for the response, so the there are products that cover the swirls and others that removed them, that is clear now.



In a a nutshell



... as far as scratches on clear coats go wet sanding is out of the question?. :confused:



Back when I was growing up the car manufacturers didn't bother with clear coats as newer cars have now, therefore compounding wax was the answer for those type of finishes.



But based on what I have read, we are just covering these up if we have a car with clear coats, I mean the scratches will show up again once we clay the car again.



You know maybe this is a Taboo topic here since it hasn't been addressed in the past....

you want to polish them out by hand or pc.....i'm new just thought i'd help before u wetsand!:xyxthumbs
 
Wet sanding isn't out of the question with clear coat finishes. All clear coat is.....is paint without pigment. Therefore you can do the same things with clear coat (sanding) as base coat only. You do have to be more careful, as you don't see the paint coming off when sanding, and it's very thin. You don't want to go through the clear into the base (or worse!).



I think you've got to give more info on what you are trying to do. As Polaris mentioned, you have different processes to use with scratches vs. swirls. With swirls, you wouldn't need to use touch up paint. Just a polish, swirl remover, or possibly a clear coat safe compound (in extreme cases). With scratches-keyed car, cat running across the hood etc.-you would need to look at touching it up with paint. Again, as Polaris said, you may need to use both the base color touch up paint as well as a clear coat paint, to blend it in better.



If you are doing touch up painting, I've heard of a product called Langka (spelling?) that is also sold by Mother's polishes as a paint chip repair kit that you use to blend in the touch up paint rather than sanding it flush. I haven't used it, but have heard that it's not without its charm.



As well, as you mentioned that scratch repair hasn't been covered, you could look in the "learn" section for articles by DavidB on this. I think the main reason it isn't widely discussed is that to do it properly, you need hands on experience. Just giving a brief outline that covers it in general may not be detailed enough for someone with no prior experience, and they may actually damage their paint more than it was. (Paint is thin-if you forgot to put a grit # down, or someone figured it was taking too long and went for 60 grit to get things moving, you'd be down to bare metal right quick!).



Just my thoughts. Hope this helps some.

:bow ....and thanks for giving it to me straight. I have a few scratches on both doors cause by frozen brushes on a stationary car wash http://www.autopia.org/forums/showthread.php?s=&threadid=33936



Since I was only able to IMO cover them with Turtlewax color wax, I'm still waiting for my PC, NXT and mostly good weather to again tackle these, in the meant time I'm reading and buying other products mentioned on some of the very informative threads and I came accross the sketch above on my 1st post in this thread so I had to ask.



Thanks for all your valuable information. :xyxthumbs
