Block sanding ?

[rustover]

Well yesterday I blocked out the lid to the cover, which I thought should have been the final blocking. I had already blocked the slick sand out in 80, did 2 more coats block with 180 and re-shot with epoxy using a 1.8 tip for build. I'm not sure what happened. It's like I was blocking it for the first time. I think its straight now but I ended up blocking it in 180 and it needed another round of epoxy so today I shot it with 3 coats of epoxy and when I block it I will try 320 first. I was hoping to catch the lid up to the cover but that didn't happen.

I'm already fighting the temps here in VA. I'm thinking of putting it on hold until Spring and switching back to metal work on the camaro. As it sits I would just leave the lid in the fresh epoxy, but what worries me is the cover is already blocked to 400.

I have a spare bay, so it will be out of the way and safe, but what would I have to do in the spring to get started on the cover again. Could I just clean it really good and final sand with 600? Thanks

Leave in the 400,then come spring, clean then do a coat of epoxy sealer then base it.

I would at least scuff after cleaning since the primer should be fully cured by then. A lot depends on the situation as to scuff or sand 400/600. It is better to make sure that the old primer has been "opened" up so to speak. I have learned the hard way to do everything to prevent having to go back and redo something.

Thanks elwood. That's what I was thinking as well. I'm still working on it. As long as it doesn't get real cold I may be ok. SO far at 30 degrees outside Ive been able to maintain 72 in the garage. We will see how it goes. If I cant finish it by the end of December I will wait until after winter.
