How would you repair this ?

PostPost by: crypto » Sun Sep 04, 2016 8:44 am

Recently had a departure into the grass field and when coming off the paved road the edge of the car floor hit the ground with the result below. The moulded steel bar in the sill was bent upwards and the floor cracked along the bar for about half a meter. Inside the thinner stiffener bars were also bent.
The question is, how should I do it to have a lasting repair ? My idea was, to cut out the fibre glass below the bar, straighten the bar from below and then joining sill and floor together. Comments much appreciated.
Thanks Peter

Dear Peter

I am more familiar with the +2 and I am sure someone else will comment on straightening the reinforcement bar.

With regard to the GRP I would make the main structural repair from the inside, you will need to get down to decent clean glass mat before you do anything - is that black stuff underseal?

Given the experience with my +2, I would want to get a minimum of 2 layers of 450g matting, 100mm to 120mm each side of the damage internally - probably with some narrower strips (50mm -75mm) where the reinforcing bar runs, then you could make the external repair with a couple of layers of 300g still going past the damage a reasonable amount but always making sure you get down to good clean glassfibre before you repair anything.

Just my thoughts, good luck.

How recent was 'recently'- I ask because I suspect more damage and cracks will likely reveal themselves over the next few weeks. The reinforcement is glassed in in numerous places even going up and over the rear wing. Impact forces will have travelled from one end to the other - I hope you don't but you could get cracks as far back as the wheel arch. Just my twopenneth but I'd suggest this is one of those times to involve your insurers (you are required to tell them anyway even if you don't claim). Get the damage properly assessed at an approved repairer and let your insurer pay for it - that's what they are there for.
