Big Girtha Build Part 13, Epoxy Fillets



Pick up any excess epoxy from the ends with a Q-tip dipped in alcohol.
Set the model horizontal and let the two facing fillets start to set up.
Epoxy will run! Be sure the fillets are level while they set up.
After the epoxy sets up for a few minutes, you can pull up the tape dams. While the epoxy is still be tacky you can smooth the edges where the tape dams were.

I didn't get a picture of this -
Put on a disposable glove and pull the vinyl over your fillet finger tight.
Dip your finger in alcohol and shake off an excess drip but leave the finger wet.


Run you wet finger down the still setting fillet.
Your finger should be wet enough that the alcohol can break down the edge and smooth it into the body tube contour.

Let these two fillets dry before moving onto the next facing fillets.

After you spray on primer you can easily see any high or low areas in the fillets.
Wrap some 220 grit sandpaper around the same dowel and sand down any high areas.
Follow with another shot of primer/filler and sanding down to 400 grit.
