                • Q:

                  Hello,

                  I have a 2013 wrangler. I want to replace my factory flairs with metal tube flairs. but to mount them I need to drill holes into my body, so I can install nutserts.
                  my major concern is corrosion forming. Where I live they use a lot of road salt in the winter. so could I use this to seal the nutsert to the body?

                    A:

                    No Jamie, this is not an exact sealant to fix a leak in the oil pan. Please refer the Permatex Liquid Metal Filler (Part No. 25909) that repairs cracks or porosity leaks in cast metal parts and fills small holes, cracks, and perforations in oil pans, stake bed holes, door panels, cast metal parts. Here is the technical data sheet link for this part. URL - file:///C:/Users/aapwebcare/Downloads/25909.pdf

                    Hi Rafael, glad to assist you! No, this Permatex # 81158 is not to be used for engine gasket applications. However, we do offer the Permatex #29132 this can be used for crank case halves, transmission case halves, valve covers, center and end covers (transmissions), cam covers, exhaust manifold seals, timing chain cases, side covers, clutch housings. It resists gasoline and other damaging fluids. It is able to withstand 350°F (177°C) continuous, 400°F (204°C) intermittent temperatures.
