Hey guys I just bought a 2010 f150 its red candy metallic. What would be a good wax to bring out the metallic flakes in the paint?
The most important thing you can do to bring out the metallic flakes in the paint is to make sure the clear layer of paint is as clear as possible and you do this by removing any above or below surface paint defects, like swirls and scratches.
It's the prep work that is responsible for 90% of the end results, (or higher).
After you wash the truck, pull it out into bright sunlight and inspect the paint for swirls, like this...
The difference between Rotary Buffer Swirls, Cobweb Swirls and Micro-Marring
They don't have to be as bad as you see on this BMW but these are what we call Cobweb Swirls and they are common in clear coat paints even if a car or truck is brand new.
A show car finish won't have any swirls, here's the same car...
So you want to inspect your truck's finish and make sure the clear coat layer, the top coat is truly clear and defect free. If not we can help you improve it but it might mean more than just applying a finishing wax which is what your question is about.
also it has a lot of plastic chrome whats a good product for that
Plastic Chrome can simply be washed and then waxed with whatever wax you're using on the paint. Avoid abrasive cleaner/waxes until you've tested the wax on the plastic chrome first to make sure it's not leaving scratches.
Wash REALLY WELL.
Chrome is fairly impervious to anything and will last a long time if you just keep the chrome clean. When dirt builds up on chrome it attracts moisture and this will lead to corrosion and chrome peeling and flaking off.
Besides washing, you can use a dedicated chrome polish or even cleaner/wax if you see water spots or stains.
