Have taken on a major resto, having stripped it i am in the process of sanding out every bit of rust inside, treating with vactan and then repainting using two coats of hammerite (obviously it wont be visible once a new interior goes in but want to make sure it wont need doing again for a long time), there is also a bit of rust underneath in places so would i still treat this with vactan and then maybe go over it with underbody seal or is there a better way to tackle it??

I tend to use Hammerite or Rustoleum underneath but this question has come up countless times with a long list of potential solutions, all of which are good and/or personal preference. I'm not as all keen on underseal though - you can't see whats going on underneath.

thanks covkid so would i treat the metal underneath the van the same, ie sand the rust down, paint with vactan and then paint with hammerite (i think its the metal straight to rust paint ive been using) rather than using underbody seal ?

Lots do like underseal. I've just never been keen on it. I did mine with Vactan followed by Rustoleum underneath although Hammerite similar in many ways. Makes it easy to jetwash and easier to see if there are any probs emerging. Waxoyl is excellent stuff too. I guess you're talking about the sections close to the sills but underneath as these tend to rust first. I gave it all a good clean. wire brush and treated as above.

This thread might be useful too.

Don't take my word for it as the only solution. I think we all have our own methods on this one.

Incidentally, Mercdoctor and I played with the ALDI spot gritblaster on seams yesterday and were really impressed by it. You go through a fair bit of grit so not the most cost effective way to tackle seams but it did leave them spotlesses clean, removing rust easily and it does a more thorough job than wire wheels, dremels and the like. It actually brought a smile to both our faces as seams have always been a terrible area to tackle successfully. Takes seconds to clear quite long lengths of seam to shiney metal, ready for sealant and paint. Big compressor and good eye protection (goggles) a must though

I have had one of these for a while. For about £20 if i remember right they are a cracking piece of kit. I find it better to zip tie the recycle bag on as the velcro is crap. Yes there is waste with the grit but its worth it.

Yep, does the job Jim. Narrow spot but thats perfect for seams. Not found anything that did as good as that certainly. Goggles a must though - grit does bounce about. I think I first flagged up this bit of kit two years ago but only got around to using it this week. No adjustment for grit spread that I could see but plenty of rubber fitments for different surfaces to help recycle grit.

Grit blasters are great. Best thing I ever bought for doing work on my van. Try to get crushed glass rather than sand... its much cleaner to use, better for your lungs than sand, cuts better too.

I just got my christmas present. The misses got me a 20 gallon pot blaster....... So much better than the little spot blaster at the big bits (obviously). But the little one will still get used because its great for the more delicate/intricate jobs.

I been told never to use sand as it can cause silicosis (I think thats the name) and it doesnt sound pleasant. On ebay you can get 25kg of glass for about £20.

oops double post

I can get 25kg for 4 euros here in Ireland.... its probably the only thing in Ireland thats cheaper than the UK at the moment!

The pots are really great. I think mine is a 10 gallon one. Only thing I have had to do is replace a couple of the ball valves, as they wear down over time....easy to find at any plumbing supplier though.
