Is this appropriate to use on an automotive chassis? Does it need acid metal prep, primer or top coat?

Yes. I used it on my chassis and under side of body. I used 2 coats rust bullet first, then top coated with the rust bullet black shell. Best if sprayed, but I actually brushed it on and it turned out suprisingly nice, just need to work slow to prevent air bubbles. I used it on my jeep rebuild so it was more function over fashion, but if it were a hotrod I would have sprayed it. Still get tons of complements on it though. Can send some pics if you want to get a look at it. Shoot me an email at tahoereeves@gmail.com

Tom, I love the eternabond but I was using it to fix seams on a metal roof. For that the best prep was Acetone but I'm pretty sure that stuff will not play well w/ your rubber roofing. I can't speak to how much you'll need because it really is based on the amount of dirt, mold you have. My suggestion would be to pick up whatever cleaner you'll need at your local hardware, home depot or lowe's and just return what you don't use. You definately need it as clean and dry as possible. If you put it on right that stuff ain't coming off. Hope this helps.

Not sure what you are using it for, but if your planning on doing a permanent long term repair I would replace the metal. Por has been a big pain in the butt for me. I'm running into problems using it to restore a car right now. I wish I never used any of their products to be honest with you. That said if you are making a temporary repair it sticks to sand blasted or rusted metal. Scrape the flaky rust off and clean it with a wire wheel use there metal clean and apply. Granted there is a place and time for por15 but it's very hard to top coat and takes a long time for all the processes to be completed. There support line is usually pretty informative though.

I did not use any primer and where I placed it was pretty smooth, once the sun hit it, we had great seal. I would suggest a fairly clean surface though.

The bumper is powder coated back and the finish is not glossy like paint. The powder coat base can be used as a primer.

I have sprayed garage cabinets to truck bumpers and plastic fender flares with this stuff. It should adhere fine if you prep the surface well.

No, this is strictly for maintaining the shine and luster on chrome components. You want to use a rust eliminator for prepping metal for paint. Possibly a primer to do so.

Hi Arnold - The glossy mirror surround is not primed, though it does take the automotive paint very well. I have not had any problems since painting directly onto the glossy outer shell. Hope that helps.

I have not used it for that purpose. There are many excellent automotive products made just for what you need. I would look in the automotive detailing dept of your favorite auto store.

I spray epoxy primer and it's pretty thick... You should be fine... Spraying latex.. 3m had one of the top primer guns out there for automotive industry., nice thing is this gun comes with a gauge and you can control how much psi goes into the gun... I bought this gun from this site and love the purchase I made.. It comes with a 1.8 nozzle which is pretty thick for most primers.. But mainly it's trial and error if you don't know.. Another key thing to note is that all spray guns require a good compressor since paint guns tend to use allot of air... hope this helped..

Car antifreeze already has built in antimicrobial properties. If your using this in a PC. Assuming your not doing sub ambient cooling and not mixing aluminum and copper, straight distilled water is better. Glycol can leave deposits and gunk. Plus it will stain your lines. I have even heard of it breaking down acetl top blocks.

I have not tried it on glass. I have used it on anodized aluminum, 500 denier Cordura nylon, high-impact plastics and polymers. None have needed a primer coat, though it probably wouldn't have hurt.

It will probably do fine. My problem with this unit was that it didn't last very long. No air compressor is required. I don't know why you would need 2 coats of primer. I generally get by with 1 coat of primer and 1 coat of paint unless you get cheap paint. The Poly top coat may require a different nozzle size than the paint and primer. It is generally quite a bit thinner. Good luck!

If it's a rubber roof you might want to check with the "Liquid Roof" folks before you try it. I had to use the primer on mine because of the rubber roof manufacture. Ours is on a Fleetwood coach.

I am sure it would do a good job of cleaning and would probably protect the contact for a time but after cleaning I would use an inhibitor grease that you should be able to get an Automotive parts store. I use inhibitor on my battery terminals as well. Hope this helps.

To be on the safe side, I would clean the sufface with TSP, and then use the primer. I would also use a hard bristle brush during cleaning, to remove any loose sealants, or coatings. Be sure to caulk around any roof vents before application. Hope this helps.
