Gelcoat query

[MatthewG]

Hi all,

I'm trying to get my Q back on the road after a long break. She's been stored outside and badly needs a polish but what I'm finding is streaks that seem to somehow be deep within the gelcoat. They aren't coming out even after a good polish. I've attached a picture of a bit (pre-polish) to try and show what I'm talking about. Have any of you seen this before? Is the fix just to use a cutting compound instead of polish? Or am I going to have to just accept that this is inevitable on a 24 year old car? (Possibly related question: how much is a respray these days?)

Any thoughts very gratefully received.

Matthew

This happened to my saloon at 18 months. Quantum paid for several cars to be painted as the gelcoat colours they used were not UV stable . Polishing or cutting is only a temporary solution .

Hi Mathew.

My 2+2 Yellow going the same way after 20 years.  Heard it said that a respray will last 10 years but I am sure many make them last longer so 20 gel coat is about it.  Wondering what to do with it mayself and looked at home paint systems.  

A professional respray can cost £3-4K.  Much of the cost is time and the prep required is massive.  So some have done a lot of that themselves.  But the prep has to be vey good for a modern gloss finish where every little thing will show through.  How perfectionist are you?  Gel coats often need some crack repair too.

Also you cannot let them put the car in an oven, it must airdry at low temperature or the body can distort.  

Best of Luck

Hi

As previously mentioned the gelcoat can be 'cut back' using 1500-2000 wet and dry followed by a cutting polish but this has a limited life and the streaking or fade marks will tend to reappear.  Yellow gelcoat can be particularly susceptible to dark streaking or shy,s once they are present there is no bringing it back and paint or wrap is really the only option, we at Quantum can offer free assessment of the gelcoat and a polishing service and full paintshop facilities (highly experienced in GRP) at discount rates for Qs 

Regards rob

Hi

Q2-002 had the same problem - was red, then went very pink.  I had a respray carried out, but it cracked and crazed after a couple of years.

I have now rubbed the paintwork down so it is flat, and used a product called 'Presto Pro PBR Paint Sealer' for Gelcoat. 

Basically you smear the clear liquid onto the car with a paper towel, and then rub it smooth with another paper towel.  The product then cures via UV (sunlight!), and hardens to a tough polymer coating.

I has not got a full gloss back to Q2-002, but is has now got a uniform colour, and a kind of semi-gloss / satin sheen to it.  I will be at Curborough if you want to have a look at it.  I have also polished it with AutoGlym as well.

It cost around £100 for a 4oz bottle, and half a bottle has done my 2+2.

Best regards
