Group: Forum Members Posts: 36, Visits: 118	Hi all, I have made a few parts which have a few pin holes, whats the best/easiest method for removing these, do you just mix a bit of resin with fast hardener and keep applying until the hole is filled and then flat off or is there a better method? cheers Lee.

It does not allow the resin to flow and get the surface you want. They have other backing materials they can suggest to go with the DF212... But there will be another new material which will have various weights, better clarity but will need to be cured at a slightly higher temperature. But I will say even the DF 212 has better clarity than the VTF261 (Easy Preg surface). It would take minimal experimenting to be honest as the cure cycle on the PDF is very close as I gave them that info. It is more about having an accurate and consistent oven. The breather stack is where you may need to do some fine tuning but that varies from mould to mould. Price? I know what price I pay but I will say it is quite a big saving over EC's material. Pro's. Better clarity Better surface (EC's material was the one others tried to emulate as it was very good and could be perfect but I have used both (About 100 meters of VTF261) and have had better more consistent results with the DF212. I would say the EC material is about 95% there compared to 60 to 70% of most of the others but the DF212 is 99%. Price Con's You may need to spend a little time adjusting to using it and finding a way to get the best results. (same for any material you are not used too) This is straight out of the mould. No lacquer or polish it was just pulled out and I took a photo...
