Polish to a shine

Group: Forum Members Posts: 5, Visits: 123	I need some help regarding the shine of the mould. We spent almost two weeks on preparing our panel. We painted it and then sand this down to an absolute shine. It was 100% perfect. Then we applied 9 layers of mirror glaze wax. When we pulled the plug for some reason the paint stuck to the mould. We did manage to get this off with thinners but was left with a few spots that we had to repair the plug. (wax additive + gel coat) First question is why did the paint stuck to the gel coat – any tips? (2K Auto Paint) The plug was sanded down and now we are trying to bring it to a shine. We used 1000 grit and then 2500 grit sandpaper. There are no other deep scratches on the plug and the polishing cream does not remove the 2500 grit scratches. (Black Tool Gel Coat) Should we worry that these small scratches will transfer when using mirror glaze? I saw on e-bay a product called Micro-Mesh that has a grit size ranging from 1500 up to 12000. What is the standard out there? Is there a Meguiars product that I could use? Tags grit sandpaper scratches

Sounds like the 2k on the plug had not fully cured. 2K that is allowed to cure at ambient temperature can take weeks to cure fully. It really needs baking to cure properly. The heat generated from the mould during curing will well exceed ambient temperature, typically reaching 60 degrees C this will cause the 2K to soften and stick to the tooling gel. Are you wet sanding? Most compounds will remove scratches from 1200's if used with a powered polisher. Warren Carbon Copies Ltd
