section two deep cracks or small fissures first

steps
after your piece cures wait until it cools fully then clean the cracked area using isopropyl alcohol on soft cloth to remove oils and dust  this prepares surface for repair without adding contaminants

after filling use a torch heat gun or straw to gently release any bubbles move quickly and keep heat moving not focused in one spot this ensures a smooth level top 

section six cure and inspect surface

let the repair cure fully on a level surface in a stable environment without drafts or temperature swings  once cured inspect if crack is less visible or feels flush run finger lightly to sense any unevenness

section seven sanding and polishing for seamless blend

if the repair area is slightly raised or edges

visible wet sand gently starting with fine grit and incrementally move to super fine to blend the level  then polish using  safe compound or polish to restore gloss and clarity
