Airbrushing Mr. Surfacer?

[klutz_100]

I guess it really depends on how deep they are. If they are very deep, putty might be an easier route to go. Otherwise filler/primer in several should do it.


However, I would be wary of spraying the whole model with this just to fill some localised scratches - you might run the risk of over filling and losing other details on the parts. Better to apply where needed - even with a paintbrush - sand, re-appley etc and then finish off with a primer?

They are just so fiddly to sand that I wanted an easy way out and wondered if this was it!!

OK, when I use the 500 grit to fill in mold lines (I'm guessing that what you mean by prototyping marks), I use a paint brush and brush it on the area that needs to be fixed without thinning it at all. Normally I brush the coat on in about 0.5-1mm thickness. Let dry for at least 8 hours and then sand away.
As it seems that you only have bits and peices here and there that need fixing.. so I wouldn't suggest AB'ing it. Be careful with the 500 grit, it wipes out details easily.
