Items to Get Great Paint
Though not many of us will have the opportunity to load up the paint gun and
start spraying, it’s important to know how a great finish is achieved. This
knowledge can help you choose a restoration shop be asking specific questions,
aid in discussions with your current restoration shop, or at least let you know
why the bill for labor and materials is higher than it would be for a basic
respray. What follows are not basic steps but additional steps and
processes that when combined with the basics will create a stellar paint finish
for one and two stage paint systems, not multistage candies and pearls. 1. A sealer primer shall be applied over the entire car
before the multiple coats of epoxy primer are applied to be block sanded. The
sealer primer seals the body from contaminants. 2. The epoxy primer must be the same color on all the panels.
Gray and red cannot be mixed and matched on different panels. Paint is
translucent, so with lighter hues, the difference in primer color underneath it
will affect the color uniformity of the final finish. 3. Using tintable primer with color added to it so that it is
close to the body color which will enhance the depth of the paint. 4. It is important to remember to use the same type sanding
boards and techniques on the doors that were used on the other panels of the
car. 5. Many shops wet sand the primer up to 400 grit sandpaper
before sealing and painting. 6. With metallic colors, the car should be painted with the
doors and bolt-on body parts on so that the finish is seamless from the outer to
the inner panels, like door jambs. 7. Any air dams, spoilers and other add ons should be painted
the same time as the rest of the car as any differences in humidity and air
pressure can affect the finish. 8. On any flexible pieces, a flex agent should be added to
the primer and clear, but not to the color. 9. On a two-stage (base/clear) system should walk around the
car after each coat dries and use 1500 grit sandpaper to nip down any
inconsistencies caused by dust, dirt and so on. 10. For added depth, 10 to 15 percent clear can be mixed into
the last two coats of base clear. 11. After a 24 hour curing time, the entire car should be wet
sanded with a 2500 grit sandpaper. 12. Use a six grit wet sanding process with only the last
coat of clear being the heavy one. The procedure begins with a aggressive 800
grit sandpaper and then moves through progressive finer grit sandpapers: 1000,
1500, 2000, 2500 and ending with 3000. 13. After wet sanding, let the car sit for another few days before polishing
out to let out solvents, then 3M polishing compound is applied using a wool pad
on a power polisher. Next comes 3M Finessing it using the polisher and finally
3M Imperial Hand Glaze with the polisher. Next, the body, is power washed to
remove the material residue from all the crevices, followed by a normal soap and
water wash. Lastly, Imperial Hand Glaze is applied by hand again. A waffle foam
pad is used on black paint to avoid swirl marks. After all the power polishing
steps, swirl remover is used on darker colors and black before applying the hand
glaze.
