What do i have to do to stop or slow down rust ,, every year im under my van scrubing and spray painting so the rust wont destroy my van is there anything new out there that will help me...im getting to old to be doing that....


I was looking at new vans and they are not even undercoated wont they rust faster if they are not mines not either so i have to keep going under there and cleaning it up each year....

 

Like? Move out of the Rust Belt?

While "scrubing" is useful for washing away salt/sand, when I try to combat rust I'm chipping & wire brushing, after washing things off. Have wire wheel fit on angle grinder & hand wire brushes. Also have a Needle Scaler that functions somewhat like a handheld, air powered, bead blaster w/o the beads. Its great for loosening any finish that's blistering underneath. I try to remove all surface rust before recoating. IMHO no amount of what I consider "scrubing" will accomplish this.

Its very important for exceptional drying after any "scrubing" since the last thing you'd want to do would be to seal moisture in critical areas. I'll wait for an unusual spell of dry weather & plan well ahead.

I've also never been happy w/any kind of "spray painting" when fighting rust "under my van". Better to use a brush & get a heavy solids, penetrating rust preventative paint, OR some of the low viscosity, moisture curing high tech paints like POR15, to soak in all the lap joints & seams. A trouble w/"spray painting" underneath is that you're limited which angle you can spray, leaving bare spots in shadows, usually the top entry points that are most critical.

One tip that's saved many a door is to periodically squirt some oil into all the door cavities, so the oil drains down into the bottom seams.

 

when i say im scrubing under my van i dont meen with soap and water like im doing dishes

im under there with a wire wheel and primer paint and im keeping it spotless...now


how about if i paint bed liner under the van on the under body what do you think about that i think that will be great!!!!!!

 

i live in pa and have trouble with rust im under the van every summer with a wire wheel cleaning and painting

now i have the idea of painting the under body with liquid bed liner has anyone tried this

im doing it this summer i will let you know how it went...

 

You guys must have places that do undercoating. You want a coating that stays fluid and never dries, everything else will just trap moisture and the rust will happen even though you can't see it. Up here we have a choice, I use a company called Krown Rust Control, they spray the underside and interior panels of the vehicle every year and it certainly keeps our vehicles in good shape.

 

ok i just didnt want to use undercoating isnt a mess under the van i wanted to keep it nice and clean but if undercoating is the way to go then thats what i will use...


thanks..

 

Preventing rust is related, but different than stopping or slowing rust that's already established.

Rust is kind of like tooth decay, you have to eliminated the decay before you can seal the damaged area & restore the surface. In this regard "undercoating" is not a panacea that can just be sprayed over existing rust "to stop or slow" it. Good "undercoating" & it's regular maintenance can go a long way to preventing rust. However its only really effective when done when a vehicle is new. Once salt & moisture penetrates deep into the seams it tends to stay there. Nothing you spray is likely to change that & covering it up will not "stop or slow down rust" in some cases it can accually accelerate corrosion.

 

I live in upstate NY and my `99 E-150 is out in the elements 365 days of the year. Driven through heavily Salted roads in the winter. Gets washed maybe once a month. My van is rust free!!! How do I do it? I bought my van 4 years ago and have taken it to Rustop to have there rust treatment applied. I have them do the ENTIRE underside (including the oil pan, rear diff cover, rear A/C lines, you name it, it`s covered). Then they drill holes into the all of the Doors and Door Jambs and apply the treatment. They also do the underside of the Hood and the Rear Cargo Door Jambs especially the TOP where our vans are noted to rust out. Sure it`s messy if you have to work on it for the first couple of months until the treatment cures, but it`s well worth it to me to keep my van`s Frame and Body in like new condition. Also have a Friend that has a `93 E-150 that he bought about 5 years ago. Had some minor rust issues on the underside when he first bought it, but he to took his van to Rustop. There Rustop treatment has virtually stopped his rust problem or seriously SLOWED it down. His van is also out in the elements 365 days of the year. We both take our vans in to have the rust treatment applied every November. Treatment cost about $130 per van. Money well spent in keeping our van`s Frame, Undercarriage and Body in Solid, Rust Out, Rot Out almost New Condition.

 

Do you guys over there have a product called WaxOyl? We use it here in the UK and it is 'the best'. Remains flexible and does not trap moisture. It will 'creep' into all the crevices and weld joins. My truck was done by the local garage for around $90 using a spray - best done every year, but not really necessary. They also inject it internally into any box sections and do the suspension as well - makes for a nice ride. You can also buy a special spray pump and do it yourself.

 

No wonder the economy is bad!!!!!!

Rust is an excuse to buy a new(er) van!
