4. After masking, scuff the area between the masking tape with a Red 3M Scotch-Brite to provide a rough
surface for the sealer to adhere Fig. 5.

Scotch-Brite
NOTE: Use Scotch-Brite on both sides of the seam for sealer adhesion.
5. Remove sanding dust with a tack rag or a lightly dampened cloth with wax and grease remover.

7. Apply a second seam sealer between the taped area that is slightly above the top layer of sheet metal
to form a continuous seal across the seam. Follow the seam sealer’s manufacturer’s procedure for
application and tooling process. Tool/Smooth sealer as required. Fig. 9, Fig. 10.
NOTE: The mixing tip on the sealer needs to be cut back to apply the heavier bead of sealer.

10. Reapply masking tape. Leave 1.58 - 3.17 mm (1/16 in. – 1/8 in.) space between the sealer and tape so
that when the base coat and clear coat are applied the sealer is completely covered and does not show
Fig. 12.

11. After the sealer has dried, lightly scuff sand with a Gray (600 grit) Scotch-Brite to produce a rough surface
for the basecoat and clear. Remove any light sanding dust with a tack rag.
12. Check the interior color to identify if the interior was painted with single stage color or basecoat / clearcoat.
NOTE: To check, use 1000 grit sandpaper and lightly sand a small, hidden area of the floor. If the
vehicle has been painted with a single stage system, the sanded particles on the sandpaper
will be the color of the vehicle (this test will not work on a vehicle painted white).
If is not a white vehicle and the vehicle is basecoat / clearcoat, the sanding particles on the
sandpaper will be white in appearance.
NOTE: If the interior has not been finished with a clearcoat system use the following procedures
using a single stage color system in the place of the basecoat/clearcoat system. Apply
medium wet coats of single stage color over the sealed repair until hiding is achieved.
13. After the repair has been scuffed using a #600 grit (Gray) Scotch Brite and tacked with a tack cloth, the
repaired area can be prepped for paint.
14. Mask the area completely. Make sure the floor and dash area are completely covered so that overspray
from the sealer, basecoat and clearcoat does not stick to any of the interior surfaces.
15. Clean the repair using wax and grease remover. Do not “soak” body shop towels with cleaner. A light
dampening will remove any remaining dust caused during the scuffing process and will remove any light
oils from the technician's hands that may have been transferred to the repair area. Additionally, be careful
to not wet the masking tape with wax and grease remover that is on either side of the repair to help avoid
adhesive from the tape from bleeding into the repair area.

16. The area to be refinished is very narrow. A Gravity Feed touch-up gun with a 1.0 fluid tip is recommended
for use.
Solvent Basecoat Procedure:
● If using solvent basecoat procedure, paint the repaired area accordingly.
● Refer to the approved refinish paint suppliers (Akzo Nobel, Axalta, BASF, PPG, SherwinWilliams and
Valspar) recommended process for cleaning the primed surface area.
● Apply DAS302X sealer or equivalent.
● Apply DBC basecoat with DX57 hardener or equivalent.
● Apply DC4000 clearcoat with SL814 universal flexibilizer or equivalent.
Waterborne Basecoat Procedure:
● If using waterborne basecoat procedure, paint the repaired area accordingly.
● Refer to the approved refinish paint suppliers (Akzo Nobel, Axalta, BASF, PPG, Sherwin Williams and
Valspar) recommended process for cleaning the primed surface area.
● Apply ECS2X sealer or equivalent.
● Apply EHP basecoat with T492 and T581 hardener or equivalent.
● Apply DC4000 clearcoat with SL814 universal flexibilizer or equivalent.
NOTE: Remove the masking tape carefully. Keep in mind the repair is on the floor of the vehicle – do
not step on the repaired area.
