Damage to gel coat

Post by grandpa2642 on Sat Jun 03, 2017 8:30 am

Both the cab section and the habitation area of my van have suffered damage from an over enthusiastic builder with an angle grinder used in close proximity to the van.

Taken to local body shops there is no problem with respray to cab area but opinion seems divided on the way to deal with the measles like rust spots that result from red hot metal filings becoming embedded in the gel coat.

Opinion 1 :- Compound rub and polish

Opinion 2 :- Rub down and paint.

After some consideration and seeking advice the second opinion has now been modified to agree with the first together with the addition of some rust preventative to prevent recurrence of measles.

Has anybody suffered a similar affliction and if so can you offer any advise?

You could try using a 'Fallout Remover'.

These type of products work by dissolving the iron particles so that the surface can be washed taking any remaining iron particles away.

These are the type of products I mean.

Bilt Hamber Korrosol:

CarPro IronX

Just spray on the surface, leave for a few minutes (but don't let it dry) the product will start to turn red as it gets to work, agitate with a soft brush then rinse off with a hose after a minute or so. Do smallish areas at a time and repeat as required. You will know when there are no more iron particles as the product will stop turning red.

Wear Rubber gloves and some form of eye protection.


The problem with using polishing compounds is that the iron particles will be so far embedded into the Gel coat that you will end up rubbing away far too much of the gel coat to get rid of them.


Hope this helps.

Thanks John. What a wealth of knowledge there is out there amongst ASOC!

When this saga started the errant builder was keen to pay from his own pocket until he realised how deep he would need to dig. So we are now in insurance claim land. 
However I will pass this info to the firms who have quoted for the repairs.

Many thanks and all best wishes
