metal filler to close pin holes on aluminium grilles all corners

We are currently powdercoating some parts for a company who is experiencing problems with pinholes in the welds and with lines and marks on the steel of the product. Our process is to sandblast the parts to remove the metal scale before powdercoating, but this is not removing these marks . This customer is very concerned about the smoothness of the finish and is wondering if there is anyway that we can fill these pinholes and smooth out the metal. We have not successfully found any type of metal filler that will withstand the temperatures needed to cure powdercoat and be unnoticeable after curing.

Does anyone know of such a product...

... or have any other suggestions? We have already suggested that they check with the welder to see if any of these problems can be eliminated before the parts ship to us, but they are still asking us to check in to using a filler of some sort.

painting rails / masking the V profile?

I'm wondering what other builders have done for painting the rails. I understand that the V profile is left unpainted.

What's the best approach to do that -- apply a strip of masking tape and use a knife to cut off the excess that's wider than the V?

Michel - Yep thats about as simple as it gets, maybe use a small fine file to trim the masking tape - works better than a knife blade.
