Cleaning up epoxy in corners

(I just posted about mold on frames. This is part 2 of 2 in my series: The inside of my Skerry is a mess.)

I did a very messy job applying epoxy between the frame and the panels. Also, there were gaps that needed to be filled in. Which I have done, exacerbating the mess (see pictures below).

Sanding this epoxy is very, very slow, and quite difficult, since it is along a line where two, or sometimes three, surfaces meet. Any advice on how to clean this up? Or whether to clean it up?

RE: Cleaning up epoxy in corners

A lot depends on what your goals with this boat are. If you're willing to accept a workboat finish, leaving the bumps unsanded won't affect the structural integrity or performance of the boat.

If you're looking to win best in show somewhere you can still pull a yacht finish out of this by going to a fully painted finish with varnished wood accents. In that case, you can cover the seams with a cosmetic layer of epoxy/phenolic microballoon mix, which is easy to sand, and smooth it all down that way.

Good luck,

We found these little "riffler rasps" to be very handy for cleaning up stuff like that:

Laszlo's right; cut yourself some slack.  Less fussing about finish, more messing about in boats!  <;-)


RE: Cleaning up epoxy in corners

   This was a constant source of worry for me.  I ended up using all of the following:

* dremel tool with the detail attachment - great when it worked, often not enough room

* Sandpaper with round rubber blocks underneath - similar to dremel tool.

* Oval regular card scrapers - requires a lot of clearance

* Lynx mini card scrapers - this was super effective, especially the oval shaped one, since it can adapt to any radius. They also came in handy for cleaning up varnish drips. Hard to spend $25 on a tiny set of steel plates but you need what you need!


but seriously consider lowering your standards for the seams :) nobody looks there when your paint/varnish is going to be so beautiful on the flat spots.
