Quoted from rufessor:You- and multiple others seeing the same reaction- have proven beyond a doubt that rattle can clear coat is not fully catalyzed. Thats an inferior product.
Sparymax 2k IS a 2 part product that works just fine, I have used it myself for filling in inserts and low spots as the OP with no ill effects.
Something else is going on, there is another product on the playfield that is reacting causing this. The OP mentioned Diamond Clear being used which is where I suspect the problem lies.
