By nature, most resins are porous and moisture absorbent. This means that if you leave it in any liquid for too long it can start to become soft.   Paint Blitzer is still highly effective at stripping paint from resin – see some of our reviews for example of great results stripping resin miniatures! This being said, we do not recommend submerging your miniature/s for longer than 30 minutes and not using it more than once on the same miniature.   Additionally, we recommend waiting for at least 1 hour after using Paint Blitzer on a resin miniature before attempting to prime or paint it to ensure that any moisture that may have been absorbed has entirely dried.   Harder, less porous resins such as ‘Forge World’ resin are less porous, whereas softer resins such as ‘Citadel Finecast’ are much more porous. Please therefore use discretion when using Paint Blitzer on softer resins.   Please note that Unto the Breach Hobbies will not be held liable for damage that may be caused to miniatures.
