Basic Dent Removal and Refinishing - Part Three
|Blow and Tack The Panel:||Using a blow gun, thoroughly blow off the entire panel. The air pressure
from the spray gun will kick up dirt from the darndest places, so it is better to get it
After blowing off the panel, use a tack rag and lightly tack off any remaining dust particles.
The panel is now ready for refinishing.
|Apply The Paint:||Using either a siphon feed gun or a gravity feed gun with a tip size
between 1.2 and 1.4 mm, apply a very light dust coat over the primary area that was
repaired. Allow this coat to flash-dry so it is tacky. This will provide a base for the
heavier wet-coats to stick to. If you were to start in with a wet coat, the paint would
run for sure.

When this coat is tacky, apply the first wet coat. This next coat will usually be the heaviest, and you should obtain full color hiding at his point. Lay down the paint in a vertical, overlapping pattern and push the wet edge from one end of the panel to the other. Work from the front of the panel backwards to the door edge and from the top down.
Be sure to wear proper protection for breathing and handling paint and related chemicals. Use a supplied air respirator and wear disposable gloves. Consult the manufacturers recommendations regarding the safe handling of these and other related materials.
|Blending The Door:
||When applying the color coats, leave the surface slightly orange-peely.
Acrylic enamel takes a few minutes to fully flow out and lay flat. If you are too
aggressive you will get runs in the paint. This takes practice - lots of it!
Allow enough flash time between the second and third coats of color. The third and last coat will be a very light wet coat. The paint is already wet and less is needed on this last coat.
Immediately after applying this last coat of paint, carefully peel away the masking tape and paper on the front door edge. Be very careful not to touch the wet paint on the fender.
Spray a continuation of the last coat into the front edge of the door. This band
should be about 3 to 4 wide.
|Blending The Door, Continued:
|Now pour out one half to three quarters of the remaining paint in the
spray cup. Add blending reducer to the remaining paint until you have about a 50-50 mix of
blender and mixed paint.
Spray this mix over the front edge of the door and extend this band into the remainder of the door an additional 6 to 8 beyond the first blend coat applied previously.
