I'm planning to have a first go at clear coating one or two small pre-preg parts that have turned out with moderate pin-holing and smallish surface voids
I was considering coating the affected areas with epoxy, flatting back with medium grit paper and then spraying.
Can anyone recomnend a tried and trusted 2k paint system and the size range of gun nozzle I should be looking at for good results?
Thanks
Mark

The Duratec Sunshield stuff sounds great, but I don't think it's available here in the UK. I had thought that it could be used in lieu of applying an automotive clear coat on top, though, but I get the impression it's just useful as a surface primer?
I don't tend to find flatting back coating epoxy too bad in small areas, but getting a decent application with a brush is difficult which seems to lead to problems getting a uniform gloss finish on whole parts without re-coating a few times.
I've seen this product and it sounds like it might be a good primer, if nothing else, but wondered if it was suitable as a topcoat assuming that pinholes had been filled and the surface suitably keyed beforehand?

Anyone used it or can recommend a decent 2k clear topcoat?
Cheers

Hi Mark, Sorry to dig up an old post. Did you ever get hold of duratec sunshield in the UK? If not many find an alternative? Sounds such a great product at filling pin holes!

Wow, that was a thread revival No, I didn't, as the UK Distributor (AOC resins) didn't seem keen on importing any at the time. That said, feedback on it from reliable sources on here seemed to...
