Sherwin Williams CARC drying time

[ajsmith184]

I sprayed my M1009 5 days ago...Noticed today it still seems "soft" and can be scratched with my fingernail. This normal? Its in a garage kept at 65 degrees. I need to put another coat and wondering if its still to early to do so...Thoughts?

Carc takes a long time to dry.

AJ,

I shot my trucks with Sherwin Williams water-based 2 part CARC and don't remember it being that soft after 5 days. Although, it was much warmer when I shot my trucks (highs in the 90s and sunny skies).

Hmm...Im kinda worried, although I know I did everything right..It has to be the cooler temps....Maybe Ill see if SW has a technical hotline I can call..

Get a kerosene forced air heater and put it in the garage. and let it bake for a full day.

Is it the waterborne CARC? It requires a certain humidity to cure.

Yeah, it is waterbourne....I turned my heater up to 70 before I left for work today..it is a natural gas burner mounted on the ceiling, pointed down at the truck.....We'll see.....I dont have SWs number on me today, I did see it on the can..If I cant see a difference Ill call them tomorrow.

I have never sprayed it in winter, mine has always dried great and I primed so I did not need a second coat.
