Seams

Hi all knowing TSSC members.

I started digging around the seams and had to dig out a ton of filler. Has anyone any idea how I fix the rust and re-seal them? I'm thinking Krust treatment and after that I'm lost! Iv'e dug out as much as I can with a Stanley Knife and wire brushed the seams as far as I can........

Many thanks in anticipation of setting the forum on fire with this one!

Get hold of a black Scotchbrite disc for your electric drill. It's a lot more effective against rust than a wire brush. You'll still struggle to get properly deep in there - the seam is designed to be a horrible rust trap and there's not muh you can do about that - but you'll be closer.

I had new front wings and a re-spray about 20 years ago. Last year a 6" length of painted filler fell out one seam, nothing lasts! :angry: However, shiny metal underneath, my "bodge it and run" alter ego say fill and touch up. :ph34r:  My "proper job" ego say "It'll all have to be done, both sides. You could get the dents and cracks in the bonnet fixed at the same time and a re-spray"

BIAR wins, for the moment.

Yes, the bane of my MK3 GT6 too - filler was always falling out. A good sprayer / bodyshop will have the professional solution in terms of flexible sealer - the car equivalent of 'Painters Mate' or whatever.

For that seam, a good wire brush on a drill - one of the flat circular ones with long bristles - will get as far in as possible, then treat well with a good rust killer. Jenolite / Kurust will be as good as can be.

I wonder if a Dremel thin steel cutting wheel run along the seam with virtual no pressure hence not cutting will clean the joint up a little, alternatively their fan style disc wire brush (3/4in dia) but watch out for the wires coming out they do stick in you!

Pity we didn't have weld thro seam sealant when our cars were built.

Hi again Pete. Thanks. I'm guessing PU means polyurethane? Is there a particular brand or kind I should use?

Thanks

Tioger seal is a common one, but there are many makes. Sikkaflex is teh original, but there are about 100 sikoflex sealants so getting the correct one is tricky.

With 2K paint I have used Toolstation PU40, and all is well. The club used to sell "heavy drip" sealant which is the original stuff, hard stuff to find!

Well that's that problem solved, new wing and you can be sure the join I say clean

Not cheap though, at £250+ per side?. I`ve yet to tackle mine, and not looking forward to it!. Even Arch repair panels are £40, a throw!. Hopefully the inner wings will "rescue".!
