How to repair deep scratches

[TechnoFunc]

I am looking for guaranteed solution to repair deep scratches got prime coat. really i found many way for the same like automotivetouchuppaint, paintscratches.com, and others.
i have not previous experience so i need advice

Hi and welcome to the forum since this is your first post...

I've been answering the deep scratch and the rock chip questions for years and the first thing I point out is most people have unreal expectations.

What they hope for and expect is that after they are done with the repair work that the panel will look like there was never a defect in the paint.

That's a nice and worthy goal but a lot of times, for most people, getting close or getting the paint better is good enough and the best they can do.

Not saying this describes you TechnoFunc, just pointing out what I've seen over the last 10+ plus years answering these types of questions on detailing discussion forums.


The above said, check out these two very in-depth articles... and good luck...

How to fix a deliberate deep key scratch

I used DR Color-chip recently. For the $, did a nice job. Can you see the chip...yes...when you look for it. However, from 5 feet away...most folks will not see it and that is good enough for me. My car is dark so not sure about other colors.

At the beginning I would like to thank you for your quickly replay. I already uploaded scratches photos to my profile you can take a look about.

For as long as I've been using specifically vBulletin and PhotoPost, I have no idea how to upload a picture to my own "profile" let alone how anyone uploads a photo to their "profile".

I upload pictures to the "photo gallery".

Big picture is, read the threads I provided, seem my comments in Richy's thread. Then do your best...

Hi...and......to AGO...TechnoFunc!

IMHO...
A guaranteed solution, for any proposition, boils down to its falling
within a region of feasibilty (and its optimization therein), or not.

For this particular case (guarateed deep scratch repair)...
-The feasible region (deep scratch) seems linear---lying within a plane, so it should be easy
to find an appropiate (guaranteed) answer by utilizing the following formula:
p = x + 2y...{Where: x> = 0, y> = 0}


To Wit:
-The theory of linear optimization says that the maximum (and the minimum) value of the
objective function p will be found on the boundary of the feasible region.

More specifically, it will occur at one of the vertices of the polygon formed by the feasible region...
(and possibly on one of the sides, if the max occurs at two adjacent vertices).

To find the maximum value of p...
1.) Draw the feasible region, to help keep track of what you are doing.
2.) Determine the points of intersection of the constraints (basically, the vertices of the polygon formed),
by solving the corresponding equations.
3.)You will then have a set of points (x,y) representing the boundary of the feasible region.
4.) Plug each of these points into the objective function p, and see which one gives the maximum value.

NOTE: If two vertices give the same value, then every point on the side between them will also give that value.


Hope this helps some!!

I looked for your pictures to "see" them and try to help but was not able to locate them.

If you have uploaded them "somewhere" and you know where they are at then copy and paste the link to them here or insert them like this...


Here's a picture from our gallery "inserted" using the [IMG] tags.
