Hi there,

So I am making carbon parts for my motocycle. It goes well, but I really don't get the finish properly. Basically, after the de-moulding, I sand the whole thing (as my mold can still improve) and then put a glazing surface of UV clear epoxy (OK, not an easy composite product cause I did not know easy composite when I bought it !). Thing is that I work at OK temperature (well, it's cold in my garage but I use a heater right next to the part), and do the glazing using a brush....and it never workds out as I always have some brush marks on the part. It's never super smooth. So is the use of a paint gun the only really good way to go ?

Thanks !

Yeh unless your part is completely flat, it's impossible to get a perfectly flat finish with a brush application. You either need to spray it, or you need to sand the brush strokes out and polish the epoxy back up again.

Really the best thing to do is improve your mould. 

Thanks for the info...I will use a paint gun...and start working on getting better moulds !
