While UV DTF transfers can survive the dishwasher, hand washing is best for longevity of the sticker.
For best results, hand wash only. Dishwasher NOT recommended.
No sealing is needed.
When used on keychains, chipping could occur. Thicker designs will last longer than thin lines.
UV DTF stickers are great for outdoors and will tolerate most all weather with no problems at all. Safe for automatic carwashes.
Clean your area to be free of dust and oils. Apply decal as you would any sticker starting from one side to another slowly pressing out air as you go.
