Filler or Fibreglass?

As summer is approaching I want to do a temporary fix on the rust holes that are allowing water into my cab:

I have a repair section and going to get it welded but due to the poptop being a pain to remove and trim having to be peeled back etc I am worried the job will escalate into a long one and the van will be out of action for too long. Seems more like a winter job.

So basically I am looking to minimise the leaking (aware it will prob still leak slightly).

Should I go for filler or fiberglass kit? Any advice / tips?

Thanks

Get a small tub of davids P40,
http://www.amazon.co.uk/Filler-Glass-Da ... B003HJMTPA" onclick="window.open(this.href);return false;
apply to some plastic such as tescos bg grade :shock: and apply this 'poultice' over the hole might stuff something into the holes first, then because you have applied the filler to plaggy you can smoth it to your hearts content :D when dry peel it of,
its a bodge but will sort you quickly, its waterproof and dead easy to whip off when you come to do a propper job
mike :ok

I would go for filler as a temp repair, you can always use some aluminium mesh to strengthen the filler until you have time to do the repair panel :ok

Filler is porouse and p40 isnt , p40 is the easiest way.

That's great advice ordered some of that filler and some mesh encase holes too big :shock:

So i smother the plastic bag bit in filler and slap over the hole and leave to dry? What do I do if it kinda sags into the hole a bit? add more when set?

What grade paper will I need to flat it back after to leave it flush for the rubber poptop seal?

I am a little unsure how to tackle the corners also as they are not simple holes and are rotten to the rubber seal. Should I pack and use same filler approach?

This is bodging advice :shock: practice first on anything simmilar. you dont want to fill the hole with anything thats going to be hard to get out later when you do the job properly, so stick a ball of paper or anything simmilar in to fill the void. get some plaggy and apply the mix to an area just a bit bigger than the hole then when you lay it over the hole it shouldnt sag too much cos you filled the hole didnt you....press it down on the edge with your fingers , you can work it about fine, it will set in 10-20 mins if mixed right, then peel the plaggy of and sand it a bit, with skill :lol: you can get a nice finnish that should do till your ready. corners are just the same , you might get a crease in the plaggy and hence the filler, no big deal.

I've got some small holes to repair too. But how should the metal around the holes be treated? Should they be ground back to bare metal, or can they just be wire brushed and maybe treated with some Hammerite treatment and then have the 'poultice' applied? Also, excuse my ignorance, but what's 'tesco's bg grade'?

As a bodge I still wouldnt put any balls of paper in any hole. If anything, use bits of plastic.

One dried, there is something you can put around the windscreen seal that is quite runny but seals up any small holes. Frosts may well do it

Its my p*ss take of tescos. any decent plaggy will do, I will trust this is a temp repair? but either way grind the paint and rust etc off, do treat it with somesort of rust paint even red lead or hamerite, use owt you like to support the covering of the hole,
but bear in mind whatever you do , will need to be removed after to do it right.

Yes, I intend it as a temporary repair. It's under the rubber tread of the step along the passenger's side door.

The worst rot I've ever heard of was a camper that turned up at an MOT station here in COV and the sills were completely gone (ie not there) and in their place was expanding foam shaped to look like sills and sprayed over.... :shock:

It gets me how much time and exspense people put into fillering things. :rofl
It must take forever to put all this filler in some of the jobs ive seen and it still only needs redoing within a couple of years :run
