Hello,
I bought an old B reg. VW T25 in July and am looking for good quality information on what I can do to repair various rusty bits as don't have sufficient funds for complete body makeover. I am contemplating getting a Dremel 4000 rotary multi tool to help with some of the necessary work to get the area's back to metal before attempting to repair.
Can anyone give a quick overview on what things I would need to buy and how to go about this please, or if you are aware of another thread where this has been covered, I'd be grateful for a link or similar.
My initial ideas are using a small 'taffy hammer' and pain scraper to get off bubbled paint and then using the dremel to see if I can get it back as close to bare metal as possible.... is this the wrong way to go about it??.... Thanks... J

Pretty universal for automotive rust repair. You lose. OK - let's see what I do and have done/witnessed that worked best to OK for a while.
Best: Cut entire area of rusted metal out. If you see it on outside you'd be shocked how far it's advanced unseen behind that area and will grow right back faster or slower on how nuts you go.
Decent: Use whatever tool works to grind off all paint/rust down to shiny bare metal. It may make holes in just doing that so come back if so and try for a picture of what you see for ideas.
IMO still in making it decent is to use a "Rust Reformer" product. It's milky water based and will react with unseen pin hole rust and turn black when dry. It kinda works but there's always more behind what you are looking at to come haunt you later. That product is your primer as well if you just want to paint the finish color over that if no more work is involved. Assorted "Bondo" products can fill small thin defects in your prep work sanded and primed for paint and look OK.
Quick and look better only for a while: Wire wheel brush it/sand it and paint it with a brush with as close a paint you can find.
* What you really want to know is how general underside of the car is and any possible structural rust or full blown holes and how important in holding the thing together. Placed where you would jack it up with a floor jack or notches for these for the jack that comes with the car must be strong - no faking problems with that and if worth it you would send that out for real pro welded in metal strong enough or decide this car is much worse than you thought under there and decide whether it's worth the effort at all.
You said you didn't want to spend too much but know what you are dealing with looking hard now. Yes if this was some unreal rare thing to make 100% new again you could and people do but you don't want to know how much that would entail.
Beware of the claims of the assorted products out there. Pretty much you are probably just going to slow it down and look presentable. For some "I don't care areas unseen" like under side strong but showing oil it and spray grease over that does slow it down a lot and repeat as needed.
Mostly rust is a car killer so don't expect to cure it,
T
