I just got my cab back from the blaster/body man and it's epoxy primered. Before I put it back on the frame, what is the best way to finish the underside of the body? Zero Rust over the primer? Paint it the same color as the rest of the cab?
Thanks. | | | | | | Anonymous Unregistered | | Anonymous Unregistered | The ZR works better if it is applied directly to the metal so if it is already primered I would suggest painting it with either the top coat you are going to use or some good enamel paint. The stuff available from Tractor and Supply has worked well for me on my trailer and would probably be more than suitable for under the cab. I assume you would be going with your basic black for that area anyway. | | | | | Joined: Aug 2004 Posts: 56 Wrench Fetcher | | Wrench Fetcher Joined: Aug 2004 Posts: 56 | REDGREEN,
I just got my '40 GMC cab back from blasting and it also has been epoxy primed. I turned the cab on its nose, scuffed the epoxy and applied an ample ammount of 3M paintable undercoat. When the undercoat dried I then re-primed with epoxy and finish coated with one-step black urethane with a flattener added so that the cab bottom would be the same satin finish as the frame. You should always scuff epoxy primer if it has been allowed to dry for a while. I am not sure if you need to re-prime the undercoat but I always use an epoxy primer or sealer before finishcoating as it prevents bleadthrough and is supposed to provide the best adhesion for finish coat. I added the undercoat as I plan to drive this truck regularly and this should help to deaden exterior noise. Hope this helps. gelee | | | | | Joined: May 2004 Posts: 204 Wrench Fetcher | | Wrench Fetcher Joined: May 2004 Posts: 204 | RedGreen,
Another option for you ...
Heculiner. I just got my cab back from the blaster. I didn't have it epoxy primered so I applied Heculiner directly to the bottom side of the cab. It cost me $59 for 1 gal and thus far I really like it. When I am finished with the body work I am going to give it 2 more coats for sound proofing. It looks very professional when you are done. I can send some pic's if you would like to see it. | | | | | Joined: Dec 2005 Posts: 257 Shop Shark | | Shop Shark Joined: Dec 2005 Posts: 257 | Thanks for the options, guys. I will probably use the 3M undercoating on the epoxy primer. But I have a little more time to decide as I'm taking the cab back to the bodyman on Monday. I found too many flaws in his gold-plated bodywork. I called him and told him that for the price I paid, he's going to get it right. | | |
