1. While having a discussion, Technician A says that lead body filler was designed for use on older, thicker, mild steel body panels. Technician B says that It should not be used on modern thin gauge, high-strength steel body panels because the heat can cause panel warpage. Who is correct? REF;368 a. A only d. Neither Anor B b. Bonly c. Both Aand B

The correct answer is b. B only.<br /><br />Technician B is correct in stating that lead body filler should not be used on modern thin gauge, high-strength steel body panels because the heat from the welding process can cause panel warpage. Lead body filler is designed for use on older, thicker, mild steel body panels, but it is not suitable for modern thin gauge, high-strength steel body panels due to the potential for warpage.
