Recommendation for body seams please

[Knockwurst]

Hi,

I've eventually got the rear lower wing panel on. Still needs finessing (whacking with a hammer) at the wheel arch as the replacement panel was too large.

I've welded the seam between the wing and the valance every couple of cm. What product do you guys recommend to fill the remaining gap, that will not react or crack once painted. I remember a post a while ago about this, but can't find it.

Cheers
Simon

Lead load it and the jobs done once, forever.

It's ok going old school with lead loading but lots of places on a stag hold hard to get at places. I spent ages painting the insides of panels with zinc rich paint. If you then go about applying extreme heat with a blow torch you leave big burnt areas inside panels. I used seam sealer. I used weld through primer and seam sealer tinned and applied with a small hard brush to force it right inside the gap. I prefer to soak the joint firstly in primer too let it run in to all the nooks and crannies.

Sikafix or similar polyurathene mastic last for ever

It's ok going old school with lead loading <snip> If you then go about applying extreme heat with a blow torch you leave big burnt areas inside panels.

The chap that taught me about lead loading (he'd have been about 115 years old by now!) stressed the importance of using as little heat as possible. The lead for bodywork is a lower melting point than plumbers solder, I forget the numbers now but the important thing is that it is a tin/lead mix that has a wide 'plastic' range to allow it to be smoothed on just like Plastic Padding. If you use too much heat it just falls off the panel. Burning any paint of the inside of a panel should not happen.
He demonstrated his skill in the technique by wiping an edge on a door panel to close up the gap which was too wide. I never achieved that level of skill at all, but I do know that the Australian factory that produced Triumph body shells would lead load the spot welds on the wheel arch return lip. That made a nice finish!
