70_chevelle Jan 13th, 04, 5:59 PM How long do you guys wait after laying down the last coat of primer before sanding & shooting the paint? I've already shot and block sanded 4 times and the body in my opinion is near perfect, then I shot one last coat. I plan on wet sanding the last coat with 400 then sealer and paint. I was just wondering if waiting a few days or weeks would bring out any filler problems that can be corrected on the last wet sanding session... Lee baddbob71 Jan 13th, 04, 9:22 PM It depends greatly with the type of primer being used, what are you using? 70_chevelle Jan 13th, 04, 10:59 PM It's house of kolor KDA2000 DTM primer. Lee feedphillipnow Jan 14th, 04, 5:01 AM Hey guys, I was wondering the same thing here. Im prepping up. Does primer color make a huge difference, or is it mostly the base coat? Maybe thats too broad a question. Nice site Lee :D feedphillipnow Jan 14th, 04, 5:03 AM How long a process did you go through painting that 70'? Not including any body work. I hear alot about people waiting too long or not long enough after primers and base coats, theres alot to learn. graemlins/hurray.gif baddbob71 Jan 14th, 04, 9:55 AM KDA 2000 DTM primer, I'm not familiar with this product but I assume it is a direct to metal primer (DTM), From what I know of the current House of Kolor primers available, most of them are an epoxy based product which mean they are a catalyzed primer. Refer to the tech sheets for proper cure time relavent to temperature. Most paint & primer products need a minimum of 60degrees F to cure within the advertised window. And from what I've been told every 10 degree drop in temp from 60 doubles the time needed to cure. In my opinion waiting a week before the final sanding is optimum, you will notice a difference in hardness with the primer after waiting a week vs. next day sanding, indicating that indeed the primer is fully cured. Just my opinion here, others may differ. Bob | ||
