Regaining Sanded PETG Colour: Heat Didn't Quite Work for Dark Parts... (lemmy.blahaj.zone)

Continuation from this Post: https://lemmy.blahaj.zone/post/36954883

After many of you Suggested that Heat could be a Potential Solution to Regaining Sanded PETG Colour, I got myself a Heatgun Capable of 600c°.

While it did Improve the Colouring, Especially for Darker parts it wasn't Enough. To be a bit more Specific, Both Green and Yellow Parts Fully did regain the Colour Red Improved a Lot, but not quite Satisfactory And Black did make a Difference, but its not Nearly Close enough, being a Matte Dark Gray instead of... Black

I've noticed that the Black only did regain its true Colour once actively Melting and Warping which doesn't help... Otherwise its a Light/Dark Gray Matte Black.

So I think the Heatgun Method doesn't quite hold for Dark Parts. What other Methods of Regaining Colour are there?

I do still have MEK that I could Try. I also Heard that Clearcoat could Work and that there are 3D Printing Specific Brands, should I give that a Shot?

Not OP, but that search brings up a bunch of different products on AliExpress: black paste, white paste, sprays, creams, liquids... Do you know if it matters?

Thanks for the tip, regardless. They're only a few bucks each, so 8 could try a few, but if you have one you know works for PLA and/or PETG, I'd appreciate knowing what worked for you!

Edit: I just thought to look at your gallery again and saw the headlight restoration bottle in the background in one of the pics, so never mind!

I saw your edit but yeah. It's a clear liquid. Watery.

It actually has a really pleasant soap-like smell.

I apply with a folded paper towel. You could use a sponge to make sure it's 100 % lint free. But paper towel seemed fine for me.

I basically applied it like if you were using nail polish remover.

There are probably different approaches. I don't think it's going to matter too much. Just note its intended to be a wipe-on. Not a soak. Not a slather-on.

So it is going to go far and last you for many projects.

I think this is the same stuff.

I've bought it twice on AliExpress with different labels. But seems like the same stuff. Can't seem to find the last one I bought. (The one in the image).
