Would it be effective to apply Rust Seal over Rustoleum Rust Reformer, or any rust reformer for that matter? I have rust at the bottoms of my car door seams and would like to remove the rust with rust reformer and then apply rust seaI and then KBS Clear Diamond Finish. I don’t have a garage to work in so the complete KBS system would be difficult to implement.

Yes, you can apply RustSeal over fully cured Rust Reformer that has been scuffed up slightly with 300 grit.

 

We recommend a solid color top coat over RustSeal when the RustSeal will be exposed to sunlight on a consistent basis. We do not recommend a clear coat (like DiamondFinish Clear) over RustSeal.

 

For car door seams, most people would coat over the RustSeal with touch up paint from your car dealer.

 

Please let us know if that helps and if you have any additional questions.

This definitely helps. Thanks!

Do you recommend any particular preparation to the rust seal, other than the scuffing, before applying the solid color over it?

Also, once I paint over the rust seal, is the clear diamond finish over the solid color a good idea?

As long as the surface is still clean, simply scuff with 300 grit. That is all you need to do and the solid color top coat will adhere very well.

 

Please let us know if that helps and if you have any other questions.

Many thanks for the continued answers. Also, I had one more question. Once I paint over the rust seal, is the clear diamond finish over the solid color a good idea?

Yes, you can put DiamondFinish Clear over a fully cured UV stable solid color top coat. This adds gloss and durability.

 

Please let us know if that helps and if you have any additional questions.

That definitely helps. I have another question. If I am not able to apply the rust reformer on the same day as I apply the KBS Rust Blast, do you have any suggestion  s on how I should prep the area before I apply the rust reformer? 

As long as the surface stays clean out of the elements, you do not need to do any prep when apply another coating over a surface that has been etch with RustBlast.

 

Please let us know of that helps and if you have any other questions.

What would be the best way to prevent Rust Reformer from getting on the outside of my car door while I apply it to the inner lower door seam?

It is always best to mask off areas you do not want coated when painting.

 

Hopefully that helps. Please reach out if you have any additional questions.

Thank you. I taped off the outside door and applied rust reformer to the inside lower door seam. When I removed the tape I noticed that some rust reformer still got to the outside door. I used KBS #1 Thinner to remove the rust reformer from the outside door. Was that wise? Would this damage the paint on the outside door?

We have not tested KBS #1 Thinner for wiping fully cured coatings (as this is not what it was designed for) but in general, KBS #1 Thinner should not damaged fully cured coatings.
