Hi, IHi, have a class c with an aluminum roof that has some rust. Should I sand down rust and use primer before using kool seal, if so which primer?

Yes, you must use the Kool Seal primer first and then coat with the Kool Seal product.

My suggestion would be to sand off any rust first. If its a large are then I would go Sherwin Williams for the primer and go with their recommendation for the metal primer. If its a small area then rustoleum should be fine. I would plan to apply 3 coats of Kool Seal. If you do go to the paint store then I would take the can of Kool seal with you to shake it. Its thick.

Certainly cleaning the surface is recommended but primer is not necessary. this is a great product and is like rubber when it dries. Be sure to wait until the outside temperature is at the right heat to dry.

it would be recommended to sand the rusted areas so you have a clean surface/ roof to ensure seal. However, primer is not absolutely necessary due to nature of the rubberized sealant. KST makes a primer that is meant to take a topcoat though another similar primer could be substituted.

There is an undercoat on Amazon made for application to bare metal and will ensure best result. Always wire brush or sand oxidized areas

what ever you dont want to show peeling so on wire brush sand paper so on by no means do you have to get rld of all the rust this paint stops the rust and encapulates it remember they suggest to top coat this paint after proper drying you may use a color on top if you wish i suggest regular rust olium

This is good for lightly rusted surfaces but for heavy rust I use POR-15. Try the sample pack first and be sure to follow instructions, very important. Good luck on your project.

Go to HomeDepot. Go to where they sell Duct-tape. Get the aluminum tape for outdoor use. It looks shiny silver roll of tape. I get the one with the highest temperature outdoor tolerance. When you get back at your trailer, clean the surrounding area really well with some dishwashing soap and water. Dry it really well. Take some rubbing alcohol with some paper towel and wipe the area lightly. Don't need to rub it. This will make sure there are no greasy area left. Take the aluminum tape and cut a piece big enough to cover the hole. Take the backing paper off and apply it over the hole starting from one edge of the tape, pressing and rubbing the tape as you move slowly over the hole with the tape. Do not apply pressure over the hole with the tape just go around the hole. You don't want to puncture a hole through the tape over the drilled hole. After you are done, put a bead around the edge of the aluminum tape with the Dicor rubber sealant. This will prevent any moisture later on to be creeping under the aluminum tape. If you can see the hole inside the trailer, you can put some clear silicone caulking sealant in the hole and wipe it smoothly and level with the ceiling. Save the aluminum tape and sealants. You might need it in the future for any other roof repairs. I check and inspect my trailer roof every so often throughout the year especially before winter and before the rainy season for any possible leak potentials. I hope this helps. Happy camping!!

Yes. I would definetely recomend Rustoleum self etching primer. Worked great for me!

Interesting question. I used it to stop rust only on some parts I intended to paint. Since it chemically bonds to the metal if your intent is to eventually rechrome or repaint the part it may interfere with the process and require completely sanding it off. If parts are pitted this could be a real problem. Also when it dries it turns black which cosmetically would not be very attractive

Take some high grit sandpaper (400 wotked great for me). Wet sand it. Try to remove as much rust as possible. You are going to primer the piece with high heat primer. Worth the investment to do it right.

Your best bet is to email rustolem and ask them your question. I had some concerns about their products last summer,and i emailed them. They answered all my questions in a very timely manner and were very helpful. I wish you luck!!

I guess I should have answered "Don't Know". I know on my application, that was was meticulous on surface sanding and prep. However, if you are dealing with metal and moisture can get to the metal, you are going to get oxidation which will start the rust process. Hopefully, someone will have the answer for you or you may have to inquire with the manufacturer, The GB Weld Company in Texas. Sorry!

I used this product around my chimmney and other areas of roof flashing with great results so far. You might want to sand {Scuff} the metal and wipe clean with 50/50 alcohol & water first. I still used an outdoor caulking along the edges first. Hope this helps.

just sand/polish nicks, burrs and rust. then, clean/degrease as necessary. then, apply. reapply for a darker effect.

I just use some today, and you do have to rub it sometime to get the rust to come off. I have seen the metal turn black and some time metal gray when the rust was removed. I love this product, it just saved me some tools that had gotten wet and rusted badly. I thought I was going to have to throw them away but it saved them. Well worth what I spent when I saved my Harley Davidson gas tank that rusted inside when it sat to long.

I would clean the rust first by using a wire brush or sandpaper then wipe the surface. Then apply Plasti-Kote. Let it dry as it turns black. Then you can paint over it. Sand prior to painting if desired.

I would suggest a cleaner/wax. Sealers will seal any contaminants in; for this reason, you should always clean the paint as well as possible prior to application.

Rust reformer dries flat black and acts as your primer. Clean all loose rust and flakes first (wire brush) for a good smooth result. I was very happy with this product and my results!

I would only use as primer on rusty metal surface. I would still use this on the auto dent to get any possible remaining rust. It turns rust in to a hard protective surface, then just paint over. It goes on milky green but turns dark brown when dried.

No, not unless the rust is removed, primed and then sprayed. I used it after sanding, a bonding, priming, matching the paint and then the clear coat. It might help over a fresh scrape. once there is rust, it has to be repaired. Hope that helps.
