In my exasperating journey to paint my V2+, I've learned a few things that I wish to share.
So far, I have purchased 3 clam shell replacements. In preparing my 1st top (I used the top of the original DJI V2+), I used rustoleum blue gloss and w/o explanation decided to apply a Krylon satin clear coat. That was my first mistake. Krylon (a lacquer) is incompatible with the rustoleum and wrinkled in spots. I was told it was a simple matter of not letting the blue gloss cure. So I sanded down the wrinkled spots and waited 3 days for it to cure. Tried again, and after speaking to various experts, they told me I needed to wait for 4 days. Once again I sanded it down, and then, waited 10 days. A Kelly-Moore guy told me to use a primer. I used a rustoleum white primer. Dried 3 days. Again painted the blue gloss (no satin). Success.
I then decided that I wanted to paint the bottom half. I didn't want to dismantle the electronics (yet) so I bought a new clam set. I painted it with the primer and waited 3 days. I then applied Krylon chrome. It wrinkled immediately, but for some reason I painted the remainder of the plane noting that the wrinkling was localized to a few spots. Well, the plane turned into a complete mess, because the Krylon chrome is incompatible with (any) Rustoleum primer. So after speaking to Krylon they suggested I use Acetone to remove the chrome lacquer. I started slowly with a brush and then progressed to using a tub (to contain the splatter). I was happy that both the primer and the chrome seemed to dissolve. BUT, on close inspection I noticed some very fine cracks in the plastic (none appeared to be completely through the plastic. So I continued cleaning with a brush and then with a rag, and then, I noticed the plane was coming apart!
Supposedly this was an original DJI part, but I suspect a copy with inferior plastic. OR, there is something I don't understand about the use of acetone.
So now, I have ordered two more clam shells from different sources. Who knows what I will receive. In the mean time, I have a plastic tool drawer that I'm using (again) to test paints in the process of drying.
My ignorance about painting plastic is showing, but I tell this tale to help others who might make the same mistakes.
