#1 1 step forward, one step back - Bonnet flanges loose

Post by alunwill » Sun Jun 22, 2025 11:07 am

I thought I was well underway towards getting the body shipped off to the paint shop but with the bonnet off the car I thought I'd inspect the inside panels!

What's apparent is that all panels, headlight diaphragms etc. have separated (or in some cases not been sealed since replacement) from the outer shell to varying degrees.

What's the best way to tackle this. Remove one panel at a time and re-stick the flange or remove them all and start again.

If it's the latter, are there any dimensional drawings available to make the job easier!

I've gone through all the Monocoque blogs which are very good but they don't provide any positional measurements.

Also, what's the advice on adhesive, 3M-4200 or Sika-Power 4720.

Sika 4720 and you’ll need air powered gun to apply it. Read the instructions fully, clean back to bare metal before assembly.

Use the Sika it is a far superior panel sealer. Modern cars use just this product to attach structural components without any nuts, bolts or screws etc. Very difficult to remove when cured.
