Definitely helps. Just need to decide between DIY KBS Strip or have them sand blasted. Thanks.

So good to hear! Thank you for letting us know. 👊

It is always best to remove as much of the unknown black coating as possible. That said, it is NOT mandatory to strip all surfaces down all the way to bare metal. After that, yes, clean with KBS Klean and then etch with RustBlast. Hopefully that helps. Please reach back out with additional questions.

I did two more coats on those plastic wheel well liners and they look unbelievably good! Thanks!

Today, I started prepping all of the front end parts I have removed from my project in order to do the 3 step system with Rust Seal. After one pass with KBS Klean in order to just remove all of the built up grime and dirt, I noticed many parts have a black coating on them that is partially coming off already. I'm unsure if it's original paint or an undercoating of some kind. See photos for an example of what the coil mount and radius arm looks like after a pass of KBS Klean, scraping and using a wire wheel to clean all of the grime and loose rust and black coating off. Do you think the leftover black coating will be a problem if I remove all of the loose stuff, KBS Klean and use Rust Blast? Or does it needs to be stripped completely? Thanks for your help and Happy Holidays!

Yes, 220 or 400 will absolutely get the job done. RustSeal cures to .002" (2 mils) per coat which is the size gap RustSeal filles. Always apply RustSeal in THIN coats and never medium or heavy coats. That is key. Please reach back out with additional questions.

Can any other grit sand paper be used? I have 220 and 400, no 300. How big of a gap can rust seal fill?

Yes, that is what you have stated and we have considered this in all of our answers. Re-coating RustSeal can be done once the first or consecutive coat is dry-to-touch and does not leave a fingerprint which is typically within 2-6 hours depending on temperature and humidity. This timeframe may be longer on the inside of a tank because of the lack of airflow. RustSeal color does not matter. This is NOT recommended and discouraged.

Just too confirm the tank will be filled with water when in use? How long between coats do I wait? Does it matter what color I use as safety blue would allow me to see where I apply it better than black? an I just use denatured alcohol acetone to clean the seams prior to application?

Yes, for a powder coated seam surface, lightly scuff with 300 grit and then clean well with KBS Klean, rinse, and let dry. Yes, if the coating is being brushed, RustSeal will work great for the seams inside. What other questions might you have?

So do I still need too sand the seams with the sealer. Also because I am just doing the seams inside, will the rust seal also work?

For the inside of a tank, you will use Tank Sealer. Tank Sealer Directions -> https://www.kbs-coatings.com/tank-sealer-directions What other questions might you have.

Ok, actually its the inside of the tank I would be sealing the seams. Refer to page one of the thread to get a better ideal of what I am talking about. Also note there there will be non coated SS rivets at the seam.

Because you are looking to "seal the seams at the bottom" of the exterior of the tank, we recommend RustSeal because it is designed to be brushed on versus Tank Sealer, which is formulated to be rolled around and drained from the inside of a tank (where it is not feasible to brush). Tank Sealer and RustSeal are the same base formulation with the main differences being pigment load and viscosity. RustSeal is more heavily loaded with pigments and Tank Sealer is thinner making Tank Sealer perform better for applications inside a tank. Based upon that, what other questions might you have?

Hmm, Rust seal over tank sealer. Please clarify why this product is better for this application over tank sealant I used on the first tender.

For a powder coated surface, lightly scuff with 300 grit and then clean well with KBS Klean, rinse, and let dry. Then apply RustSeal. Always thin coats and at least two coats. RustSeal Application Directions -> https://www.kbs-coatings.com/rustseal-directions Please reach back out with any additional questions.

Its powder coated inside and out. I'm looking only to seal the seams at the bottom where the tank joins the base plate.

Are you looking to coat the inside of the tank or the outside of the tank? Where is the powdercoating? Outside of the tank?

So I have another tender to seal. This time its a brand new one that has been Powder Coated. Will the sealer stick too it?

If the surface has been kept clean, simply apply more coats of KBS UnderCoat with no prep required. If the surface needs cleaned, use KBS Klean to clean the surface, then simply apply more coats of KBS UnderCoat with no prep required. The pictures look fantastic. Thank you for sharing them with us. Please reach back out should you have any additional questions.

They are sitting under a covered porch after drying. Amazing difference though on these 38 year old plastic wheel well liners. 1. Side by side comparison of plastic wheel well cleaned only with KBS Klean 2. Side by side comparison of plastic wheel well cleaned with only KBS Klean 3. Wheel well just before using KBS UnderCoat in an aeresol 4. Post KBS UnderCoat and looks brand new!

Are you keeping the surface covered and clean or is the surface exposed to the elements?

Hi again, I went with the KBS Undercoat Rubberized and absolutely love the texture out of the aerosol. However, I underestimated how many cans I would need and was only able to get 1 1/2 light coats on my wheel wells. Once I order more, what would be the prep needed to continue adding light coats since the current coat will be cured by then? Thanks.

Yes, you apply the black paint over RustSeal and get incredible adhesion. Apply the black paint once the second or final coat of RustSeal is dry-to-the-touch and does not leave a fingerprint (usually 3-6 hours depending on temperature and humidity). You can use Cavity Coater, lanolin based oil, or Nhou once RustSeal is fully cured. Be sure to check out RustSeal Application Directions -> https://www.kbs-coatings.com/rustseal-directions Please let us know if that helps and if you have any additional questions.

With the other brand “P**15” in the past with “their” product I would normally spray Rustoleum black while the product was still tacky before fully cured and got really nice results also saved me time not having to sand the whole frame prior to applying the top coat. Is that not a good idea? I got your satin black rust seal and was going to top coat it with rustoleum. Also which product won’t affect your product when it comes to “oil” undercoating? Lanolin based products or should I use NHOU?
