Hi,
I'm replacing the truck floor of my '70 valiant and will be welding it in from the original spot welds. I have cleaned and rust blasted the areas, however i plan to weld through prime the areas i intend to weld first then rust seal the entire area (chassis rail) prior to welding. I'm doning this so when the weld burns up the rust seal there will still be protection from the weld through prime. Is this a good idea and will it work with the rust seal? Thanks Paul

You are correct. You will want to do the RustBlast, then weld, then the RustSeal.

You can find complete directions for RustSeal application here: http://www.kbs-coatings.com/rustseal-directions.html

We also have very helpful instructional videos for the application of RustSeal that you can watch online for free here: http://www.kbs-coatings.com/instructional-videos.html

In addition, we also have a Flow Chart for the application of RustSeal here: http://www.kbs-coatings.com/rustseal-flow-chart.html

We also have our How-To Section which has two series of common step-by-step procedures for the application of RustSeal found here: http://www.kbs-coatings.com/how-to-use-kbs-coatings.html

And before you begin your project, it is always a great idea to familiarize yourself with our RustSeal Fix-It Guides found here: http://www.kbs-coatings.com/fix-it-guide-rustseal.html

Hi sorry i didn't get real clarification of what i plan to do. I will be welding parts that will not be accessible after welding. Normally i just put weld through primer in these areas to protect the welded area, but in this case i also want the extra protection of rust seal in between the folds to be spot welded together, cat i paint rust seal over the weld through primer and still get the same protection as painting straight over rust blast?

Many Thanks

RustSeal is always best on the actual surface, but if you need to, you can also apply it over the weld through primer.
