Annoying scratches in resin

1.) Epoxy Putty and sanding.

2.) If the scratches are shallow, try a coarse primer #500, sand and than finish with a fine primer #1000.

3.) Fill with CA and hit with a kicker/accelerator (not my recommendation).

MMF has it right with option no.1 I'd just sculpt the epoxy putty and remove the excess with a cocktail stick & water before it dries, as it becomes much harder than resin and therefore much harder to sand, hence possible more damage to the resin parts...

Another method that I often use to get rid of pin-holes and fill seams in Garage-kits(aka Resin figure Kits).

Get a Tube Putty like Tamiya, Gunze(I use their pre-thinned putty), Milliput dilute it with thinner into a paste, apply the past and wipe excess off, leave to harden and tidy up.

Another option would be a putty that uses a kicker/hardener that is mixed in with it, not sure what the equivalent is overseas over here we got Tamiya, Mori Mori, Sube Sube,etc.

Hope this helps, not really that different from fixing flaws on a plastic models.

I have tried all of the above suggestions for filling both scratches and pin holes and find that the primer method works best for me. I use Floquil (lacquer) Gray Primer applied with a brush. It dries fast and won't chip off around the feathered edges as most putties do. If the scratches are deep, just apply as many coats as needed to fill them. For pin holes, push the primer into the holes with the tip of a small pointed brush.

I was going to recommend a product by Tamiya called Mr. Surfacer. It comes in three grades. I used some on my NS Savannah when I used old masking tape to mask the Hull, and had gobs of old glue stuck to it when I removed the tape. Then used my Dremel with a sanding drum to sand it off, leaving a very rough, uneven surface. I thought the kit was trash, but then a friend of mine recommended Mr. Surfacer (500 Grade). I put it on, let it dry, and sanded it smooth. Now you can't tell it wass ever damaged.
