Order Of Operations
« on: July 27, 2016, 06:48:56 PM »
Hi all. Just a quick little question I have regarding refinishing a plane. The plane in question is a Lil' Jumpin' Bean. It was doped, sanded, re-doped, and sanded again. So the question is can I paint directly on the doped wood and silkspan, or is it better to spray on a coat of primer first, then sand that followed by paint. Thank you.

What effect do you want to achieve?  For 1/2-A stuff I aim for waterproof and light, so I don't put a lot of dope on the thing.

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

The effect I am looking for is simply another 1/2a plane that looks good and flies equally as well. I have used dope and such before, but the main reason for asking is that this is my first built up wing using silkspan and this alone is the reason I ask about painting right over the dope, or prime it first followed by a sanding. Thank you.

If you've sealed the silkspan with clear dope, you can paint right onto it with colored dope.  This works particularly well if you retain the natural doped silkspan look for the thing, with colored dope used as trim.  It will not be a mirror-smooth "20 point" finish.  But that doesn't mean it can't look nice.

Ok, thank you then. I was planning on trying acrylic craft paint thinned and sprayed with an airbrush, followed by a coat of rattle can Minwax Polyurethane Clear. But i think I should be alright as the dope is sealed. I will not get to painting till after the weekend. I will post progress report after it happens.  ::)
