More grp on the hole repair and headlamp fitments. Painted the finished repairs inside the body work with cheap black gloss then sat and thunked about the airflow into the rad. The guides as original allowed loads of leakage to bypass the rad so got the cornflakes packets, scissors and sticky tape out to lay out some flat plates to use instead. Still thinking though!

Two coffees later, I'm making new ducting fer the rad which will stop incoming air bypassing the matrix. These take the place of the original thin wobbly stuff and is arranged to form a divergent duct to slow airflow through the core. The exhausts are to be wrapped and body protectors used so the underbonnet heat shouldn't be excessive.

Just a curious point: I have heard that wrapping the manifolds can cause the cylinder heads to overheat . . . any insights? Sounds like the coolant should be keeping the heads temp stable, not the manifolds :? Otherwise the wrapping is said to keep the exhaust gases travelling quickly and to reduce under-bonnet heat, which its what you are looking for of course, and sounds a good idea :D

I wouldn't bother listening to them, had my Scims fer decades and had no problems. The beauty of owning a vehicle is just that----it's yours.

I've experienced a few criticisms over the years and read them all but make my own judgements and do my own thing. If I've made mistakes or found better ways I fess up then get on with it.

I need to address the air leakage between the ducting & the rad on my coupe too. There are big old gaps all the way round, which doesn't encourage the air to go through the rad at all.

Hi Ben, I'm still building the ducts so I'll post pics when it all makes sense. The verticals each side are attached at the top to the remains of the originals and the chin at the bottom with the front edge closely following the nose inside contours. There's a horizontal dividing plate across between the verticals but it's too narrow, front to back, to do any useful job. I haven't decided why it's there,

There's the large air inlet behind the chrome grill and smaller ones through the horizontal plate near the number plate mount so can't see the original purpose other than adding stiffness to the verts. I think I'll make it wider front to back and angle it downwards, front to back, with the front edge just under the large air inlet. Still thinking about it though!😳

Yep, that middle bit is a little odd. I've not really looked at all properly yet & I have an after market ali rad. However, I'll await your results!

Well, got the trial side ducts somewhere near but changed the tops to fit outside the originals for better alignment and to allow the middle bit to fit and get a reasonable angle on it. Nothing's glassed in yet to give me more thinking time!

Roight, I'm glad I left some thinking time. The bumper/chassis extensions were away with the fairies and could have scuppered the whole ducting project!😳

So I bolted them to the chassis, did the measuring and marked out where the front plates would be and the angle of the triangular brackets. Result! Everything's hunky dory! They pass between the inner mudguards and the ducting although access to their fastenings will be challenging, Reliant just needed to put the bleddy captive nuts on the brackets instead of the frame!😬

More lay-ups done to re-inforce the ducting but waiting for more mat. Ordered Monday and arrived today, usual good service from East Coast grp supplies, however the mat is stuck together so has to go back.

Meantime I scraped, wire brushed and wiped more of the cr@p and underseal from the underneath.

Got fed up so attacked the rotten steel in the drivers side sill, really pleased at the high quality ferrous oxide Reliant used😳😎.

Always good to add lightness :lol:

I guess the stuck-together matting has succumbed to dampness - bad luck :(

I ordered 3.3mts but it arrived folded to 1.45 so just thought it was doubled, however when I delicately tried to part it, no joy, it looks like the starch has securely bonded or it's 600grms instead of 300.

Off t' the post office to return it tamara and phone them for a correct replacement batch.
