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

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

These guys are obviously importing Duratec products to the UK so they should be able to get it for you?

Thanks for that Fasta

Although no mention of the Sunshield product on their site, I'll get in touch to see if it is something they can supply

I know that the topic's been covered a few times elsewhere, but would also be interested to know people's favoured technique for filling pinholes prior to applying a final topcoat

There seems to be a lot of different approaches out there and, it seems, all require a fair bit of elbow grease to get a good final finish. Applying clear coat by brush in an attempt to fill the holes first, followed by flatting and prep feels most appealing in terms of simplicity, but happy to hear other opinions on this

If you can get hold of the Sunshield then it's the perfect solution for pinholes too. You can spray your dust coats followed by your first wet pass, then use a squeegee or a roller to force the coating into the porosity. Then carry on with spraying wet passes until you achieve your desired thickness. 

I do the same kind of thing but I brush the first coat which also pushes it into the porosity.

That makes perfect sense, of course

Thanks guys
