Scoring rings do not need to be visible at 50 yards, but clearly visible when pulling arrows to score. Don’t make them too deep or wide!
When OEM score rings on an old target (McKenzie) are not visible use a dremmal type tool to re-mark (ONLY on OEM foam). NOT for use with 3DTRF material – use ONLY soldering iron on 3DTRF foam.
Additional Tools for Shaping
We prefer to use a close quarter electric drill with the mentioned ScotchBrite Abrasive Pad because it is much faster, however, we have had reports from some customers that they have used an orbital sander with 40-60 grit paper to shape/finish the repaired area.
In some cases on select types of targets, you may want to fully form your target (staple form completely) and not have a flap at the side or to pour through. INSTEAD, cut a large enough hole in the center of your plastic form to pour the material through while keeping the target horizontal. This will let gravity spread the foam more evenly as it expands.
NOTE: Do NOT walk away from the scale after adding the resin!!! If the scale shuts off from no activity, you MUST re-zero the scale with an empty container of the same weight for proper tare weight in order to achieve the wanted results!!!
Guide For Estimating Volume of Material to Pour into Repair Area
Grapefruit/Softball Sized = use 150 to 250 grams of resin
Cantelope Sized = use 250 to 450 grams of resin
Watermelon Sized = 450 to 850 grams of resin
Targets that become shot out quickly; 12” or smaller girth. Example: McKenzie Beaver, Wolverine, Bobcat, Raccoon.
- Before repairing, cut out and insert a piece of 4lb dimensional foam 2”-4” thick (see pictures below), form, and pour around (encapsulate completely). The dimensional foam can be purchased from many packaging companies (outfits that make boxes, etc.). Following this trick will help extend the life of the repair and limit pass-thrus even after the 3DTRF foam is shot up.
Necessary Tools for Target Repair
- Saws All or Drywall Saw
- Small Staple Gun
- Soldering Iron 40-80 Watt – Weller MFR #SP40L or MFR #SP80L (Available at most Hardware Stores)
- 6 Mil Plastic Sheeting
- Digital Gram Scale – Available from Harbor Freight #95364 *MANDATORY TOOL
- 3M Abrasive Pad – 5” Disc with replaceable pad MFR #9419NA, pad only MFR #9410NA (Available at most Hardware Stores)
- High Speed Electric Drill – 2250 RPM
- Mixing Tool to Combine Foam Parts A & B (FREE with 1st order)
- Safety Glasses & Disposable Latex Gloves
- Mixing Containers: Clean, dry plastic jug, Plastic cup, 2 quart paint bucket, waxed popcorn container.
- Note: Containers should not be too large or much wider than needed. Your mixing tool should be covered by material when mixing. Example: 20oz solo cup is good for up to 200 grams of resin. 2qt plastic bucket is good for up to 1000 grams while the 2 gal bucket is good for 2000+ grams (see picture below).
Additional Suggested Tools and Materials

- Needle Nose Pliers – for pulling staples
- 3 mil Plastic Sheeting – for making scoring ring template
- Cardboard & Duct Tape – to back plastic (only for large pours)
- 1”, 4”-6” Drywall Screws with Fender Washers – used when gluing on ears, locs, etc.
- Gorilla Glue – for reattaching heads, feet, ears, locs, EMT conduit in legs, etc.
- Large Serrated Knife or similar – for trimming cured foam and removing loose shot out material.
- Wooden Paint Stir Sticks – used to help scrape mixed foam from the container into the form.
- Box Fan – for use when burning scoring rings.
