SDTM Cary Hardy: Clear Coating: The Final Coat

TL;DR

Final clear coating, wet sanding, and polishing process for pinball playfield restoration.

Summary

Key Claims

• Issues in previous clear coat application were caused by combination of 95-degree outside temperature, aged clear coat, and fast hardener

  high confidence · Cary Hardy explaining variables from previous video's problems

• Hardy switched from DuPont Chroma Clear to Advantage brand based on superior results on the Hook machine

  high confidence · Cary Hardy discussing material changes between videos

• Playfield must cure for at least three weeks before cutting and polishing, verified via fingernail test

  high confidence · Cary Hardy explaining curing timeline and verification method

• The clear coat mixture used for spraying contains approximately 98-99% water and a drop of dishwashing detergent

  high confidence · Cary Hardy describing spray mixture composition

• Wet sanding should progress from 800 grit through 3000 grit, stopping at 3000 to avoid hindering curing process

  high confidence · Cary Hardy explaining sanding progression and reasoning

• Using Novus 2 as lubrication between cutting wheel and playfield prevents burning the clear coat

  high confidence · Cary Hardy demonstrating cutting wheel technique

• The cutting and polishing wheel should not spend too much time in one spot to avoid heating or burning the clear coat

  high confidence · Cary Hardy demonstrating proper wheel movement technique

Notable Quotes

• “I usually use DuPont's Chroma Clear, but that's usually on my machines. But with the results I get with Hook, chances are I might actually switch over to Advantage. Because it looks great and it's solid.”

  Cary Hardy@ 3:34 — Indicates material preference shift based on recent project results; could influence other restorers' material choices

• “The most important part of this whole process guys is patience.”

  Cary Hardy @ ~12:30 — Core philosophy statement about clear coating restoration; emphasizes waiting for proper curing

• “If I do not have any kind of lubrication between this wheel and the plate field, there's a very high chance that I could actually burn the clear if I'm not careful.”

  Cary Hardy@ 12:28 — Critical safety/technique warning about cutting wheel operation

• “I'm constantly moving this pad back and forth across the playfield because I do not want to heat this clear coat or burn it or damage it.”

  Cary Hardy@ 13:42 — Demonstrates proper technique emphasis on consistent motion to prevent heat damage

• “Look how shiny this damn thing is guys.”

  Cary Hardy@ 17:26 — Demonstrates satisfaction with final polishing result; shows transformation quality
