Should I claim or pay for it myself?

I have car insurance with quinn direct ,5 years no claims(not protected). Comprehensive cost about 370E. My car was keyed along 5 panels , i have got 2 quotes for respray @ 1500 euro. When I rang Quinn no one will tell me how much my insurance will go up if I claim it on insurance, I will lose my no claims for 3 years and pay 180 excess.
So my queston is how much is losing 3 years no claims bonus going to cost me? I'm asuming less than 1500 , anyone give me an idea?
Thanks

As far as I know, it should state in your policy booklet the NCB scale. I’ll give you some basic, possibly out of date figures just to explain a point:

5 yrs 50%
4 yrs 40%
3 yrs 30%
2 yrs 20%

So in the first year, you could lose 30% worth of discount, second year 20%, third year 10%.

Also bear in mind the fact most other insurers won’t quote for 3 to 5 years, so you’ll be blocked from shopping around, meaning you could miss out on substantial savings with another insurer. Your insurance company will be well aware of this when calculating your premium.

similar situation recently - car keyed - cost 800 euro to fix. i paid myself as now have 7 years ncb and don't want to be limited from shopping aorund.

Id claim, your insurance is €370 with full NCB.
Roughly working it out

Next year would be €481 approx on a 20% NCB
Year after €444 30% NCB
Then €407 40& NCb

Rough figures only. but your combined increases is what €300 approx & x/s compared to €1,500 outta your own pocket.
Your insurance will not go much lower then €370 anyway, anyone who thinks that is deluded.
