ill share something with you guys . I've made test boards with CV .......breaking all the temp rules , and the over-mill rules .
one board was sprayed and allowed to flash , then immediately set outside in about 40 degree temp ( drizzly/rainy also , but not rained ON ) ; then dried / cured overnight in un-heated attached garage . another was cured in my basement...temp un-known , but well below the suggested range . both those boards were monitored for months...no problems . I should look around....maybe I still have them .
Ive also done test boards with HUGE over-millages . if i remember correctly , one was in the 8 mil range ( 3 coats I think) . and yes , Im talking dry mils ..... three coats shot at something like 6 to 8 mils each ( measured with a wet-mil gauge ) . that one I kept an eye on for a few months also....no problem last time I saw it . pretty sure I still have those , so Ill dig them out again . I think I did cat-primer/tinted CV and clear CV samples like that .
Ive never done over/under catalyzed samples , but Im pretty sure I know what the results would be .
also did some over-mil samples with 2 part urethane . poured on and measured at over 20 mils as it was setting up .
with that being said ....no , Im not saying that the rules of catalyzed coatings are meant to be broken . I follow them religiously .
