Hi, about to make a CFRP part using a female mould and want to know the best coating to use for the part.
I see two diffrent gelcoats on the website which are sutible for an epoxy layup, the Epoxy gelcoat and the GC50. 
I read that the GC50 gelcoat is difficult to apply by brush and I do not have the means to spray it.
Is the regular expoxy gelcoat (https://www.easycomposites.co.uk/epoxy-bonding-polyester-gelcoat-clear) easier to apply by brush?
I read that the regular epoxy gelcoat is not as UV resistant as the GC50, the part I am making will be used outdoors but mostly stored indoors and only be outdoors for upto about 20 hours per week, will UV damage be a problem here if I was to use the epoxy gelcoat?
Are there other coatings available other than the epoxy gelcoat or GC50 which I could use or Is there anything available which I could spray into the mould without requiring a professinal spraybooth and air fed respirator (I only have a regular paint spraying gun and a cartridge respirator with A1 and P3 filters).

I don't mean to start an argument, each of us is going to stick to our own beliefs and practices. My point was that I am always a bit taken a back when someone with obvious experience posts on a public forum where people who don't know any better will read comments of "go ahead, use these chemicals without proper protective equipment, you'll be fine". I just think those of us that do know about these chemicals have a responsibility to communicate that these are incredibly harsh toxins rather than compare them to barbecuing, and some people may value their health above their composites project.

Personally, I ALWAYS read the MSDS and judge the risks for myself. I've studied health and safety, I know the procedures to assess the situation and determine what I need to do to protect myself. Hazard, exposure, risk. First priority control method is always substitution, and in the case of 2 pack paints, it isn't hard to substitute it for a less hazardous chemical. That's all it takes, it isn't necessary to say that if you can't spray 2 pack paints safely then you can't produce quality composites. I certainly haven't struggled to find substitutes for surface finishes, and when it comes to the chemicals that I can't substitute, like polyester in some cases, then I make sure my other control methods are in place. This isn't taking health to an extreme, this is basic. It's not about being scared of bodily harm, it's about being aware that your health is worth more than whatever you are making.
