drywall compound mixed results. the nose gear fairing with the very large pin holes left the surface low so if you have very large holes use something else. for the main gear fairing I used primer then direct to drywall compound without scuffing. the fill wasn't very good and then a beginner mistake by applying extra sandable primer and the drywall compound lifted to the surface. so the conclusion is apply drywall compound to a well scuffed surface so it has something to hang on to and do not wet coat. the nose gear fairing that was scuffed before drywall compound turned out well.
there are those low spots from the large pin holes filled with drywall compound
the main gear fairing were a mess, behind on the table
wing tips blocked sanded, using a soft pad and the rolled scotch-brite both wrapped with some flexible 320. 320 is my final sand grit for everything. some folks like 400 or even 600 but so far I don't see the need. the paint is thick and feels like plastic when you pick up a part after a couple days. after one day the paint is still very soft so be careful not the scratch it before it cures. after a week it is hard. for example, I was painting several parts on consecutive days and stood an elevator against the wall after one day cure. it stuck to the wall. no damage done so then I put one day cured parts on black plastic. they don't stick to black plastic. go figure. also, there seems to be significant hardness change between 24 and 36 hrs. I will buff the paint after 6 months.
I noticed in this picture I have a ridge line from the block sanding. I need to take a look at that.
this one looks ok.
final surface primer, these are going to be nice if I don't screw up painting the blue color. I will use the white primer as undercoat since the bottom of the plane will be white for the blue bottom color. two coats should be enough by examination of the color cards I painted earlier.
colors, Chevy white and Regiment blue
new plastic on the table, that solvent bottle on the table is useful and a pump for the reducer can (not shown) is good
