DIY Prepreg Checklist

1)     Before mixing epoxy get out all supplies

        Gloves

        Cutting mat, pizza cutter, scissors

        Mixing cups, stir sticks

        Bruch (cut), squeegee, razor blades

        Paper towels, alcohol

        If required: Cab-O-Sil, flock, microballoons

2)     Make paper templates (number)

3)     Cut prepreg plastic

4)     Cut fiberglass, place inside plastic

5)     Mark the plastic with the templates

 

 

Epoxy Wipe Method

This is a method for preparing moldless fiberglass layups for paint

1)     Rough up fiberglass with P40-P80

2)     Spread dry micro balloon mix on the surface (ideally deeper than final surface profile)

3)     After it cures, block sand down to final surface profile

4)     Remove dust

5)     Squeegee on straight epoxy, then squeegee every bit of it back off

6)     Wait for 45 minutes and repeat, 4-6 times in total

7)     Wait for 2-3 day until it gets good and hard

8)     Block sand with P180-P220

9)     Prime with 2K urethane primer
