Spec Spot Repair II
Rust spots can be deceiving…..especially when there are a lot of unknowns. These unknowns aren’t particularly seen until one starts the restoration process by sanding the surface. Start by cleaning the surface with a good prep-solvent and a clean rag. This process will strip the surface from any silicones, wax or contaminants. This is done to prevent these contaminants from becoming imbedded in the paint surface during the sanding process. As you sand, the sharp edges of the sand paper aggregate abrade the finish – it is during this process that these sharp edges can force un-cleaned surface contaminants down into the paint surface where they rear their ugly heads during the priming / painting process – this could be in the form of fish-eyes for example.
It is important to note here, that when sanding a small spot like this, stay in a very small confined area as possible sanding to remove all remnants of rust as you can, Keep sanding until no more rust is detected. My choice of paper for removing the initial paint, rust and primer is 80 grit.
When sanding a spot, try to stay as flat as possible to prevent gouging. The end result should be a smooth transition from the paint, primer and then into the steel as shown above. After the 80 grit paper is used….change to 180 grit and blend layers into their surrounding layers.
