Best Product To Deal With Sink Marks?

[MILD]

Can someone please recommend a good product to deal with minor sink marks that result from shaving moulded badges, arial mounts, wiper mounts etc. My Dart project continues and the body is in primer however it really has highlighted a number of issues that I would like to correct prior to paint. This is the first body where I have really carried out these minor modifications and as such I am unsure where to begin when dealing with them. I do have some Green Stuff here but if there is a more elegant method than smearing putting and sanding it back I'd love to hear it. I have heard mention of Mr Surfacer but am unsure what exactly it is this product brings to the party.

Thanks in advance- I can't wait to have this one boxed up on my desk and the photos posted here!

Hey Mick,

For small areas I just use superglue, I put a couple of drops on wax paper, then I use a toothpick to apply. Work it carefully, use the side of the toothpick to even it out on a larger area, make sure you don't build it up too high, then just sand when dry, works very well for what you are describing. The more you try it, the more you get used to it, just a cheap and easy fix. Hope this helps you.

If you cannot blocksand the areas around the sinks level, then you have to use some sort of filler. Depending on the size/depth, you might get away with dabbing some Tamiya or Mr. Hobby "primer in a bottle", or a dab of superglue followed by kicker and immediately sanding, or swiping it with the filler of your choice. Don't cut corners with bodywork and paint. If you are going to customize or whatever, deal with the consequences. Small marks where you do custom bodywork are expected, and if you want good results you'll have to work for it! Just roll with the punches.

I had tried super glue mixed with micro ballons. It blend great and works real nice, specially at sand time. You can adjust its consistency adding desired amount of micro ballons. Slow setting super glue recomended.

If you are talking about the "marks" resulting from raised details being removed (by filing and/or sanding), those aren't "sink marks" but rather what is commonly called "ghosting". To deal with "ghosting", let's start with an understanding about what is happening:

Bear in mind, plastic model kits are molded under extremely high pressures (about 100 tons pressure!). The styrene is cooled, and solidifies at this pressure, which ordinarily causes no problems. However, when one sands, files, removes raised details by whatever means, and then paints with lacquers--the built-in stress of that high pressure injection molding is relieved (lacquer thinners penetrate styrene, soften the surface), causing the removed detail to swell up, reappear. I've found that the only real solution to this is to use primer, airbrush if possible. I spot prime areas where I have removed surface details or even mold parting lines, just as if I were a body shop, fixing imperfections. I then wet sand down the offending "ghosting" just to the point of smoothing down these areas, and repeat the process again as needed.

This has always worked for me when tried--I started painting model cars in acrylic lacquers in the 1960's.

I've heard that a coat of Future will also "seal" any ghosting. Never tired it myself, but IIRC MrObsessive uses that technique.

I have to second (or is it third by now...?) the super glue suggestion. By far the easiest and most consistent trick.

Yes it will.

Thanks to all for the suggestions as well as the good explanations concerning ghosting. Now I actually have half an idea what I am talking about

I will give the superglue a go and work from there.

I also like to take what i call sprue goo and spreadit over the spots . I mix Testors liquid cement withesprue until the sprue melts. I mix it to a runny consistency but thicker than the glue. I then spread it over the spots that might ghost. after that sets up I then sand it to smooth it out.This has worked to stop the ghosting.
