Using Bedliner As Undercoating

Hey this Donnie Smith and I had a question emailed to me about undercoating, see the question says, comes from Paul and says hello. I just found your YouTube channel, I'm wondering if someone might be able to point me in the right direction here. I just bought a new car from the south and live in the Northeast. The underside of the car is in perfect condition and I'm looking to make sure it stays that way in the presence of chloride they use on the roads in the winter. The car is a 2004 g35 sedan. There is a little bit of factory undercoating underneath, but the vast majority of the underside is either paint or primer. I have the engine and the transmission out this weekend, so I would like to be able to do it this weekend. Do you have any recommendations as to what I should use? I'Ve heard that people are 15 should only be used on rust and it doesn't stick well to smooth surfaces. I'Ve heard epoxy primer and nothing else should be used. I'Ve heard epoxy primer first and then bed liner on top I've heard so many stories and mixed and mixed up. I'Ve heard so many stories and mixed reports online that I really would appreciate an expert telling me what would be best for my situation. I would be glad C says thanks in advance and hope to hear from sink so Paul, probably you know if it's in good condition, I mean, as far as the surface being smooth nothing's really going to stick that good. I mean it's going to have to be cleaned real, well, degreased, real, well and sanded for anything to stick to now. If, if you sand it and there's no metal showing, you can put strip a bed liner straight on top of that, I think bed liner would work well sim, as CEOs got some bed liner. That works good and they recommend, if you do go through and there's some metal exposed that uh that you do, prime, that first then you'll have to come. I can skip that area up with 180. You know you want to use 180 on these areas or they also have a bed liner brush that works well. But if you brought this up, scuff it up with 180 and there's no metal showing you really don't need to to use the epoxy primer. So it just kind of depends. I mean if it's in that good of shape probably have that scuffed up without much metal showing and then you just come back and prime a few spots where you did burn through and then scuff that up use bed liner. But I think bed liner be the most durable out of what you mentioned. The por-15. You know that works well, but that's you know really good for up for rust, like like you mentioned. Probably the bed liner would be the best again. You know from the things that you mentioned: epoxy primer is good, but it does not hold up. It needs to be top coated because it will absorb moisture. You know any primer really is not that good of a topcoat so that I probably go with that. If that's the only product you use, if you do spray it all with epoxy with Simms SEM anyway, they recommend that you come back if you scuff that up before applying the bed liner, so a couple different options here. If you want to get a more specific question, ask me ask me: I'd be a glad to help you out a little more on that, but just uh. You know from what I see on here. I would scuff it up with 180. If you have any bare metal, you can hit that with epoxy and then come back and spray the bed liner on I'm familiar with the Sam. In fact, we've done a video just I don't have it all completed. Yet we did the inside of a Jeep kind of like what you're talking about worked. Well, there's other companies out there there's some. This was a sprayed on. I mean it looked real nice there's some other companies out there that make some roll on I've. Had students do that, I'm not as impressed with that kind of just doesn't look as as good to me, but I mean if you don't have facility or anything like that to spray it on that might be an option for you. I think. Is it a oh? I can't think of the name of it right now, but probably go to your auto parts. Store they'll have some some of them come in. A spray can now use some of that on a Mustang project. I was working on just for the inside of my quarters and all that, so you making you some spray can, you know, might can get some roll on where you roll it on, but yeah that doesn't probably work good. Anyone had sealed that off real good, where a lot of it that stuff don't get to your metal, but anyway. I hope this helps. We have more questions, you know be sure and ask you know, I'd, be glad to try to help you. I don't know what brands you're thinking about using like I said: I've used sim SCM I'll, put a link down the description for that and your parts store probably has like I said: spray can roll-on, so this kind of depends on what your needs are. You know what would be the best to use so anyway. I hope that kind of helps enter your questions. If you have a more specific question, be sure and ask and Alla I'll try to get back to you on that anyway, thanks for watching and take care and we'll see you in the next video
