I got the resin from Parts today, to use to fill in the chips on my trailer fenders. I need to get the catalyst, Simon said to get MCKP at a paint store. Is that a brand I ask for, or is that a type of catalyst? He said to mix it 2% by volume with the resin. Assuming I decide to do this myself: Does that 2% mix have to be very precise? Can I mix it in a pan or bowl? How is it best applied after mixing? How long do I have after mixing before it sets up? After its applied, what do I do after it hardens? As you can see, Ive never done any kind of gel coat repair. Should I farm this out to an expert, or go ahead and try it myself? Would it better for me to call and talk to someone at BCB about this in person? Sorry for so many questions, Im just trying to decide whether to do this myself or not. Thanks for bearing with me.
