Guide Coat is essential when performing bodywork.

When you are hunting at that jet black classic car or truck at your regional cruise in you may possibly take for granted all of the methods it took to get the car or truck hunting laser straight and the finish so “deep” hunting. A essential step in performing bodywork and having the physique of your project straight is to use guide coat. Study on as we give you some insight on why you need to have guide coat when repainting or restoring a your car or truck or truck.

The procedure for straight bodywork begins from the metal up but imperfections can be corrected through the physique filler and primer stages. By applying guide coat you can verify your progress along the way and save your self some surprises when the automobile is painted and accomplished. The procedure of guide coat is relatively basic. Usually you do your physique filler and seal the repairs with gray primer. From there you can apply a contrasting colour guide coat (normally black more than gray primer or tan guide coat more than black primer). The guide coat is misted onto the surface leaving a spotty hunting finish.

Soon after the guide coat dries you can take a extended block sander and sand the panel in an “X” pattern paying interest to how the guide coat comes off the panel. You will notice that 99% of the guide coat will come off with the very first round of sanding. If there are any significant lows the guide coat will settle in these regions and stay soon after block sanding. Sometimes you can block sand the complete panel to knock the surface down level with the low spot, but most instances you need to have to fill that region with a smaller swipe of physique filler, glazing putty or higher develop primer. Soon after you have filled that region you can once again apply a mist of guide coat and block sand. As soon as the complete panel is totally free of guide coat you are confident the panel is good and straight and will appear great when painted.

Guide coat comes in a handful of types with the most prevalent becoming in an aerosol kind which you spray on lightly. The second most prevalent is a dry guide coat in which you brush onto the panel with an applicator. This style can be sanded nearly instantaneously but does take longer to apply to bigger regions.
