Sika or Gelcoat?

[iain26]

Up on the roof for the first time to give it a little clean and found a hole.
The hole is about 20mm dia and is in the plastic moulding over the cab on my AutoTrail.
I obviously need to fill it and reseal.
Happy to do it myself, as it is on the roof so wouldn’t be seen, but unsure wether I should be using a Sika product or Gel coat or even a combination filler and finishing product.

Any suggestions please.
TIA

a 20mm hole !! is quite big.. how deep is it? if its shallow and not broken through the skin i would used gel coat filler. follows easily and can be rubbed down to blend in.
sika i think would only be a temporary repair.

if its deep you may need to do a bit of patching..

There is about 3 or 4 mm of air behind the plastic.

looks as if there was a bubble under the gel coat and its cracked revealing the cavity. can you see the fibe matting underneath?

Yes can see through to some matting

so it is a bubble under the gel coat. i would buy a proper gel coat repair kit, they are only about £10 - £15 and you get all the necessary bits for prep and rubbing down.

there are a few different types, here's an example of whats available.. <Broken link removed>

You need the RAL number that’s the colour code from Autotrail, or talk to East Coast and they might even know it.

Hi Ian, I had something similar on our Autotrail Imala 730 on the offside roof rail anchor point about the size of 20p got it done under warranty it seems they have a bad batch , it might be worth asking Autotrail if they would consider a claim.
