I hope someone can give me some advise, I purchased the Real Model Engine set for my Hobby Boss M1070. The lower part of the engine, oil pan, hoses, tranmission, are full of small holes I guess from air in the resin as it was poured or setting. What can I do about filling these? Thanks

complain and get him to send a new one.
quite often his stuff has air holes.
push comes to shove i filled the holes with Mr. surfacer 500. not perfect but it worked, sorta.

Yep I tried Mr Surfacer it pretty much sucks for this to most of the air holes are pretty deep.

If you can't get replacements, you may want to try some automotive putty. I've filled holes in a few resin pieces with it. Just fill, smooth over with your finger or a soft cloth, let dry, and sand. I doubt the holes will be noticable, if they are on the bottom.

Thanks for the tip, I will try that
