Title: New technique a brewin'
Post by: Larry Renger on July 22, 2013, 04:27:00 PM

Check out my SLC over Polyspan experiment in the 1/2A section.  Progress is being made, and the potential is awesome. (Modesty is only one of my MANY virtues)

I'm waiting to hear how good the adhesion is between the SLC and your paint.

If you get the surface buffed to a dull look all over, the adhesion should be great.   Make sure your hands are clean or have been washed of all body oils.   Maybe wear new clean gloves.

Here is a photo of the model with the wing roots painted and a bit of striping added. I still need to cut new lettering and numbers.  The paint is Painters' Choice directly over the lightly (wet 600 grit) sanded SLC.  Came out pretty darn well!

BTW, I pre-clean the surface with Denatured Alcohol on a bit of Chamois. No lint! No fisheyes, great adhesion.  My sample piece stands up nicely to heavy scratching with a fingernail

That looks great.

What's the benefit of SLC over Polyspan?  Why not just stampede to the SLC and forego time, effort etc. of the Polyspan phase?

It is tougher and more rigid than either one alone, but still VERY light weight. The film and fiber properties, when bonded together, compliment each other to the benefit of both.
