Sand Blasting of Body Shells and Components
|Sandblasting is an important technique used in both full and partial restoration, and is indispensable for a high-quality overall result.
This technique involves a blasting process in which pressurized air is used to accelerate the blasting abrasive and shoot it against the surface to be cleaned. In practice, various abrasives are used depending on the surface. It should be noted that, as their name implies, many of these abrasives are designed to wear away material.
Of course this is desirable in most cases, but care must be exercised because selecting the wrong abrasive or using excessive air pressure to apply it can quickly lead to unwanted damage.
|The most common blasting abrasives used in classic car restoration are listed below.|
|Corundum||A sharp-edged abrasive, well suited to rust and paint removal|
|Glass beads||A gentle blasting agent. Creates semi-gloss surfaces. Effectively cleans carburetors, intake manifolds, cylinder heads, etc.|
|Plastic||Non-abrasive, suitable for cleaning and paint removal|
|Nut shells||Appropriate for cleaning surfaces that are heavily soiled or covered with resinified oil|
|When sandblasting a complete body to remove old layers of paint, expertise and experience are a must because large surfaces can readily warp if- for example - the wrong blasting pressure is used, one area is subjected to blasting for too long, or the blast gun is handled incorrectly. Heating caused by the blasting process also plays an important role and often causes the sheet metal to buckle.|
