Scavenger! Build Part 21 Epoxy Fillets

After the epoxy is transferred to the root edge, smooth out the bead and remove excess with the rounded end of the Popsicle stick.
Do about half the root edge, wipe off the stick and smooth the rest of the root edge.
When the epoxy is just starting to set up, remove the tape.
You might have a slight ridge where the epoxy has gone over the tape edge.
You'll remove that with the rubbing alcohol in the next step.

Put on a Nitrile glove to remove excess epoxy with rubbing alcohol.
The higher percentage of pure rubbing alcohol, the better it will break down the excess epoxy ridge and smooth the fillets.
Most drugstore alcohol is 70%, try to get the highest percentage.

Pour some alcohol in a small disposable cup.
Dip your gloved finger in the cup and shake off the excess into a paper towel.
Run your wet, gloved fingertip down the epoxy fillet. This should smooth out any irregularity in the fillet and start to break down any glue ridge where the masking tape was.

Try not to do too many passes of the alcohol. It can break down the epoxy too much and slow down the epoxy drying times.
