seam overkill?

[jamesandtheopenroad]

Good evening fellow T25 lovers,

I'm going to attack my seams soon - not to bad at the mo but the sealer's cracking and I'm starting to get a little discolouration - before, hopefully, painting it towards the end of the summer.

Been doing my research on here and have a vague plan but wondered if it might be overkill. So here goes:

Dig out seams with dremmel (no money or space for a blaster sadly)
Lay a bead of 3M 8115 (as suggested by Mr theRev)
Dinitrol RC 900
Dinitrol seam sealers
another coat of RC 900
Red Oxide
Paint
I see you can also get something called Zinc Zinga that is zinc in a can that galvanizes to the metal - is this just unnecessary?

And I plan to do the back of the seams too.

Thank u gents and gentettes.

The 3m 8115 is a panel bonding adhesive I think? Personally I'd put a rust treatment (maybe RC900) of some kind on the metal before putting the panel adhesive on. Not much point putting RC900 on top of the panel adhesive because the whole idea of RC900 is that it converts the rust, so it has to be in contact with the metal.

PS: Where does one buy 3m 8115? Can't find any UK suppliers, just USA...

ooh, yeah, t'other way round - makes sense.

Ta!

we sand blas but excepting that you cant then dig it out, even find a hd stanley blade/knife works well , keep digging, scraping etc, use a wire wheel in the angle grinder, when you reckon youve got as much as you can out the vactan dinitrol whichever is your choice, when well dried in hit it with weldthrough or your zinc paint etc, whatver you do dont go filling it with sealer, and dont sealer till its done with your undercoats etc. use a thin and I mean reallythin bead of 3m, I will post up the link for the stuff we use , its in a tube like a big toothpaste tube , dead easy to apply, then when dry prime over it and jobs done.

I'm no expert and mostly did what mm suggest.

However, I used a similar product to vactan called fertan. I left the fertan to do its job for a few days ( it likes the damp) cleaned air dusted and a second coat until I can see the back liquid coming through the other side of the seam.

Then I cleaned area again and painted with epoxy primer.

Waited a few days for primer to set and rubbed down epoxy and applied a thin bead of sikaflex

I waited for sikaflex to dry and then another coat of epoxy. I plan to skim the areas (as long as I don't see rust coming through) and then paint with rustolium.

This "thread" is getting a bit confusing

To get back on track, to answer the question "Why" asked in response to my post = "Watching this - and you can guess why "

The reason I am watching this post is because I too have some seam rust and I am gathering information on the various methods of effecting a repair.

OK, carry on...
