REFLECTOR: Smooth Prime Orange Peel

[Douglas Holub]

The instructions say 3 coats, then sand, then 3 more coats. You guys are right-- it really does sand smooth. The fuselage and strakes look like new now.

  Doug,

   

  Do you have PolyFiber's instructions for SmoothPrime?  As I recall, they recommend rolling on six coats with no sanding in between, then sanding before applying the primer recommended for your topcoat.  It definitely is "rough as a cob" after rolling it on, but it sands smooth quickly and beautifully.  It's not a true primer, it's really a surface filler.

  Hi Alex,

   

  I primed the bottom of my entire fuselage when I primed the fillets and my nose gear wells because the fuselage is 18 years old and not really white anymore. I rolled on three coats of Smooth Prime, and ended up with some very heavy orange peel which it looks like I'll be spending the better part of two days sanding smooth again. Today I remember you once wrote something about spraying water on the Smooth Prime while rolling it? Could you refresh my memory on that, please? Will that make it flow better?

    Looks really good Doug- certainly aesthetically pleasing - and it will reduce interference drag- how much hard to tell, but you can make a fast plane a few knots at a time!  I assume that you put some bid on there before the primer... I have a measly 1.5" radius right now on the strake fuselage intersection- might go fof the increase like you did- although it might interfere at the rear windows...

    I used pour foam to fill in the intersection between the strake and the fuselage, then shaped it with some 40 grit sand paper glued around a Clorox bottle. Here's what the fillet looks like with a Clorox bottle radius. By doing the top and bottom of the wings, strakes, and winglet intersections this way, I'm hoping to pick up a few extra mph.
