Hi all, hope your new year has started well.

Just wondering what everyones thoughts are regarding new seam strips/covers. I have the clips and was intending to use sikaflex (spelling?) but wondering if the finish edge between the body of the car and seam should have sikaflex or auto body filler. I was thinking auto filler will be easier to get a nice job but any movement and the filler may crack, take in water and rust. If I use sikaflex its harder to get a smooth finish but I think it would be the better long term approach.

What have you all done in the past?

By Sikaflex, do you mean as a bonding agent?

I've used Dripcheck for my cars. Also used this in the gap between the front guard and the wiper panel.

Yeah its the stuff I used on the gutter seams and it worked pretty well, similar to seam sealer but goes a little harder allowing to be painted. I will check out the drip check, it may be a similar type product.

Hi 68Rusty

I just finished this job and I ended up sticking my seam covers on with Sikaflex auto adhesive and no metal clips.
This is the first time I've done this so I don't know if it's long lasting or whether it will remain crack free.
I also wasn't concerned about the "originality" of the appearance of the seam/body join as the van is a daily driver and I just wanted a good waterproof seal.
I just filled the seam covers up with Sikaflex, pushed them on and smoothed/removed the excess with paint thinner.
I then taped them up overnight until it all cured and overcoated with high build primer and then the main colour (acrylic lacquer).
Here's how they came up;

RUSTY.

As above, Sikaflex is so much stronger and easier. I've done two Mini's this way. I've used SikaFlex on Cars, Buses. Trams and Trains. It's great stuff!
The only issue is that the seam moulding is stuck for life. To remove it, requires grinding down the fold of the moulding, then peeling it off as two bits. However, mouldings are cheap, and if you do it right from start, they can stay on for near eternity.

My process:
Clean the seam back to clean raw metal.
Couple coats of primer
Fill new seam moulding with Sikaflex
Clamp onto seam. (G clamps, lengths of wood, etc etc)
Gently wipe excess away. Avoid using solvents (at this stage)
Leave overnight.

Next day (or at least (say) 8-10 hrs later, remove clamps and any wedges of wood etc.
The overfill (Ooozz) can simply be scrapped off using your finger nails (no good for nail chewers!)
You should be able to get all visable Sikaflex off, right up to the join.

You can now sand (240grit) lightly, than apply another light coat of primer.

Nothing looks worse than tracks of sealer down each side. All sealers flex and shrink and crack the paint and allow for rust. The above method makes it totally waterproof.

Goodluck.

Sikaflex comes off with heat pretty well - but only an option if you are re-painting.

Sikaflex is great, however I would not recommend filling the gap between the front guards and the wiper scuttle panel. This is an area does flex and will crack the paintwork over the Sikaflex.

Thanks all,
Great advise as usual from Ausmini members. I will be starting seam this afternoon so will let you know how I get on. Movement between scuttle and wing panels sure makes life difficult, I have had to use filler on the right hand wing the recreate the shape as it was rusted and rebuilt and welded. The weld is right between the join though so I hope no movement occurs there?

Cheers,

Thanks all,
Job came out well, but not as neat as the photos above. Seems when ever I get near that sikaflex it turns into a helter skelter moment for me. Glad I am done with that stuff, so damn sticky and hard to clean up!

Cheers
