Chrome-look paint problem - yellowing




Sir, I have problem in chroming our parts. When I sand the parts with 1200 Grit sandpaper and clean with Flow Additives and then apply basecoat single time and then apply topcoat, the part can be seen good chrome but there is mark of Flow Additives, but if I used double basecoat and then apply topcoat it is yellowing but the mark of flow additives couldn't been seen. please inform the solution.

Hi,
I am not an expert on chrome, nevertheless I am assuming top coat and base coat are liquid coatings. Therefore, the way you describe your problem makes me think that the base coat and top coat are not manufactured from a water white resin system. It therefore follows, as additional coats are added the darker the colour. If this is the case, ask for a pure acrylic based material as these are normally water white in colour, this should overcome your problem.
