Rear window defogger lines

I am currently working on a project the Aoshima 1/24 scale Car Boutique Club Sprinter Trueno. My Goal is to try to resemble a D1 car I saw back in 06, Ueo Katsuhiro's AE86

When I purchased the model kit, it had window defogger lines.
I saw some site that shows him removing from this:

To this.

My question is, How can I do the same? The website didn't say how he did it, so I'm hoping if anybody can help me out. I already removed the lines but can't figure the next step.

This is the website, it's in Japanese:

Thank you

sanding.

very fine grit sandpaper to remove the etched lines then use polishing compounds to buff up the plastic just as you would paint.
Quite a tough task as you have to be hard enough to affect the clear plastic but gentle enough as to not break/crack it.

But seeing as that rear windshield is more or less flat, why not simply replace it with thinner clear plastic/acetate sheet?

Just my thought, or vacuform and use the Kit part as a master

Nothing we do in modeling should ever be "hard" and certainly not so hard that you'd risk breaking something. Scale modeling is synonymous with patience, and unfortunately we have to take a lot of time to do something. When you cut sheet styrene, or a hood or door out of a model, how do you do it? Many, many passes with a very sharp knife or scriber until it pops apart. Let the tool to the work. Same for sanding. Sanding "hard" is always a recipe for trouble. Sand putty hard and it crumbles, sand plastic hard and it scratches, sand paint hard and you burn through, sand acetate hard and it breaks. Not to mention that sanding hard will leave a surface that isn't straight. When you sand, let the tool do the work. Spend an hour in front of the TV with progressively finer grits or sandpaper, and compound at the end, and you'll be astonished with the result. Fingers need not be sore (maybe tired) at the end of sanding.

My first thought at well. Should be easy to replace, even without vacuuform.

i used clear plastic for rear glass of my ae86. the rear hatch is relatively flat

Thanks for most of the info.

I got tips form a couple of friends of mine but I'll tell you guys if it is a good idea to go.

1. Use buffing wheel and use polishing compound

2. use 2000grit sandpaper

Either options sounds good but don't know which way to go

Try both :)

But if you want to replace the glass parts, read this (http://www.automotiveforums.com/vbulletin/showthread.php?t=514642), it might give you some ideas.

If you want to cut up the kit clear part (which usually helps improve the fit) you would do well to invest in a set of p/e saws which make teh job very easy and clean.

I'd just use some clear plastic sheet from some packaging that I'm sure you have laying around.

i have sent you a pm of a site i found
hope that helps you?
