First off do you guys prime ALL your parts and body? Do you primer the sprue?
I have noticed that sometimes the paint can scratch off after painting directly on the plastic, even after drying.
And second how much do you assemble things like the engine before start painting. Or do you paint each part prior to assemble.
I know these are very basic questions but I need to know.
I think I may need to primer the sprue
Actually, I never apply primer to my body, or any of my parts……[clwn]
I use primer only to find surface defects in a near completed model, or under colors such as white, yellow, orange, and some reds.
If the paint scratches off, the surface wasn’t properly cleaned before it was painted.
Some paint on the sprue, some paint off the sprue. Generally, off the sprue is less work, but not always.
Whether you paint before or after assembly depends on what is easiest and most efficient. Sometimes its best to paint some things before assembly, especially small parts. Sometimes not. Which depends on your plans for assembly.
What do you suggest to properly clean parts before painting? Thanks for helping.
Windex, Simple Green, basically anything that can cut grease and wash off cleanly, leaving no residue. I give most surfaces a wipe with a lint free cloth soaked with isopropyl alcohol. And make sure that no water lurks in hidden areas. Water is paint’s worst enemy!
