Removing seamlines from canopies

On my last build the VF-0S the canopy came with a nasty seamline, it took me months to decide which of the many techniques around the net to use, I opted for a mix of techniques and, as you can see on the gallery had great results, fist, here are the videos of the two techniques that I used:

Basically what I did was to remove the seamline with the back of an exacto knife, then sand with WET 400 grid sanding paper, after that the 1200 DRY sanding paper, and polish it with the toothpaste with a barely wet soft cloth, I highly recommend this, you'll be surprised how cheap and easy this is.

Hope you try it with some great results.
