How to Clean up Frame Rust on a Budget

How to clean up a rusty frame on a budget. Unfortunately the fender areas on this truck, both the front and rear seems to have the majority of rust with minimal frame paint left. Being that this truck was used in the country, the previous owner drove down quite a few gravel roads, which can basically sandblast any paint or finish off the existing metal components. Currently this truck also gets driven down gravel roads doing to the dump, so again it’s not really helping out this situation. Considering we live in a climate which has high humidity and we also experience winter, this type of environment promotes rust. #oemtools #rustrepair #autobody

Tools/Supplies Needed:
-wax and grease remover
-clean rags
-tape
-paper
-farm equipment implement paint
-paint brush
-wire brush
-scraper
-air powered surface sander
-air compressor
-sanding pads and discs
-oil spray rust preventative
-spray on rust converter

Procedure:
-remove any parts which will allow you to get easier access to rusty components
-wash the area using a degreaser to help remove any contaminants
-using a ball-peen hammer, lightly hit the surface of the frame to remove any scaling
-a mix between a wire brush and scraper can also be used to remove any rust scaling as well
-next grinding down the surface to remove the rest of the rust, here I am using a small portable air surface sander to remove the surface rust
-first starting out with an 80 to 120 grit abrasive pad
-a mask should also be used as this process can get quite dusty
-once satisfied, a majority of the rust should have been removed and then you can switch up to a 220 grit sanding disc
-switch up to 320 grit sandpaper as a final abrasive
-considering there is still rust pitting, this can be hard to clean so this will be chemically treated instead
-blow off the area using the air compressor to remove a majority of the dust from sanding
-give the area a wipe down using a wax and grease remover
-apply paper and tape to the areas you do not want painted and protected from overspray
-give the area another wipe down using a wax and grease remover
-using a spray on rust converter, follow the instructions as all products have different application processes and apply it to the frame
-allow the rust converter to dry
-apply a paint of your choice
-for this I was using a farm equipment implement paint which can be brushed or sprayed onto the frame
-if you can, it’s best to apply this on a cooler day
-if you have a softer brush, you’ll get a smoother finish but due to the rougher surface, the brush may not last as long
-I do not recommend using a tar or rubberized coating as they can trap moisture which can cause rusting
-the next day I was able to reassemble the suspension as the paint was hard enough
-allow the paint to cure for a couple weeks and try to keep it responsibly clean
-once that paint has cured, as an added step I have applied a rust protective coating
-rust protective coatings can be either an oil or wax spray which helps repel water and moisture
-spray the coating inside the frame if possible and on the outside
-cardboard, plastic, or a tarp can be used to prevent any oil drips on your driveway
-do not apply an excessive amount where it can run off the frame
-after dust sticks to the coating, additional layers can be applied
