I saw this on another forum and thought it something I would have to try.
For a seam filler a guy was using a UV cure product made for filling gaps on fake finger nails. Dries hard once subjected to UV and ready to be sanded.
No fumes, dries in minutes, and shouldn't shrink. I also figure you have more time to get it right before you choose to set the product.
Similar to the products shown here:

I also saw a UV cure spot putty made by Bondo at the hardware store. That may work well too.
New! UV cure fillers.

This is interesting.
The UV cure fingernail plastic is an acrylic, apparently. The regular fingernail acrylic (which is also a dental acrylic) is wonderful stuff, but it stinks to high heaven and has a short pot life once mixed.
It's very expensive, too.
If the UV cure acrylic doesn't seem to be as expensive, but the Bondo stuff may be easier to obtain.
It looks like they have several. The 930 Bondo UV Glazing and Spot Putty looks like a good place to start. They also have a 751 Bondo UV Body Filler Bondo Pint
How do these guys compare to regular Bondo putties?

Well I picked up a tube of UV Glazing and Spot Putty by Bondo. These are my preliminary test results.
The product is white and cures as advertised in a short period of time under the sun. I left it for 10 minutes in a sun that was obscured by a thin layer of clouds. The package claims it will cure between 4 and 15 minutes depending on the strength of the sunlight but will not cure under normal household lighting.
The hardened product resembles white chocolate and didn’t appear to shrink. It's has a good smooth looking texture.
There is that familiar Bondo smell but it is much less noticeable than the smell of other hobby and automotive fillers. So far so good, I am very pleased.
What has yet to be determined is how the product will be to sand and how it will adhere to plastic. I somehow doubt that will be a problem. My next step will to try it on a model and I will post my results.
