clarkspeed Posted June 4, 2021 Author Share Posted June 4, 2021 Wow I missed out on posts for the last couple days. Some interesting techniques I need to try out. I tend to use very thin sheet to fill body panels, sometimes even thinner than the Datsun panels. No gap, low heat, and typically a "pearl necklace" finish like you mentioned. Although I would never use that phrase. I always check the back side for overall good pen, but not every mm, grind to finish, and then thin bondo along with a backside coating. I rarely hammer the welds or shrink metal, just smallest negative profile I can attain (less than 1/8"). Small pinholes everywhere. But keep in mind, I build race cars, not show cars, so I'm not to concerned about getting an all metal flat finish like the guys do on TV. As long as I can duplicate the contour, no one will ever check it with a magnet. Race cars always stay indoors, and tend to be repainted often. I've never had a bondo crack or rust break through, without direct contact of course , Quote Link to comment Share on other sites More sharing options...
