Hello!
Here’s the WIP:
I’ve found that it helps a lot to hit almost all of the parts out of the box with spray paint - in my case that was a black paint by Wurth. This stops the parts from being “tacky” and “funny to touch” and highlights all the funny pattern from 3D printing, showing you which areas to fill and/or sand (sometimes sanding itself is enough). If you’re pressed for time, you need some filler that works fast - CA or better some 2 componennt automotive putty where you apply it and are ready to sand almost immediately. My biggest problem were warped parts that just didn’t want to straighten - after I hit them with hot water and straightened them they somehow tended to warp back overnight. So in cade of the frame rails I just replaced the warped portions with rails I have scratchbuilt out of styrene - I was very happy with that solution. In case of the blade I was able to successfully straighten it. With many parts if you see a problem with them it’s faster to scratchbuild them than to save what is there. Anyhow, check the WIP out for tough spots - that’s what it’s there for! Hope it helps, good luck with your build and have a nice day!
