I've finished painting my spars with Interlux
Brightside following the instructed process for aluminum
and it has gone fantastic. Now I want to do the topsides and I'm confused about what I have to do to properly fair before painting. Today I ordered a 16" longboard, Surface Putty 257, Special Thinner 216,and the Brightside color which is the same color as the two part paint
on there now (Black). From the spars project
I still have plenty of Interprotect 2000E, and Prekote left over. Here is where I'm confused. I was reading just now and it seems I can't sand, clean, and apply fairing compound over existing paint
? Can I not sand the area good wherever I need to use the putty but still apply over the paint?I had hoped to get the wax and impurities off, sand with about 150 grit, then fair and sand with the longboard, then prime and paint. There are a few scratches that actually seem to have been painted over which is crazy. They need to be faired, plus when you look at the boat
from certain angles you can actually see the woven pattern to the glass at the beam just below the toenail. I guess where someone sanded down too close to the mat and didn't epoxy
over it. I've never seen that before. The boat
is 43 years old but that can have anything to do with age as I've seen beautiful hulls older than that.
What are my options? Do I have to take all existing off to then get the surface fair?
