Hey composites wizards,
It been long hours around here working on the cabin top. So far I've sanded down the bumps, applied micro, sanded that down, and done three epoxy wipes.
The problem is that there are now small ridges/waves in the epoxy surface. Perhaps I'm a bad squeegee-er or maybe this is to be expected. The ridges are hard to photograph, but they look like linear streaks in the surface---a fatter version of the lines left by a paint brush.
I've tried sanding with 180 grit and a .032" aluminum backing plate. This roughs up the surface but the troughs of the waves are still visible.
What's the right way to solve this one? More sanding? High build primer?
If sanding, what grit would you recommend? I'm a little concerned about sanding through the epoxy shell, but I don't really know much oomph that would take.
DanH made this look so easy...
