Is Modge Podge heatproof?
No. According to the customer service representative at Plaid it will melt if heated. Neither Modge Podge or Royal Coat Decoupage products are heat-proof. Sometimes if you have a question about a product you can go to the manufacturer's website and see if they have a customer help line. The people at Plaid are really helpful. Or you can just ask us!!!
So .. there you go!
