Having used one can clear coat, it's really not that great, so 2 part clear coat is likely a must. It will kill you though, so absolutely look into PPE and do it outside.
And it really is a pain to paint frames, so... Be very careful with over spray, clear coat is meant to not come off.
I painted one from primer stage, the result from a distance is fine, from up close it's adequate, but I wish I had just ordered black and played with decals. To be fair the whole painting operation cost me less than 30 EUR.
