Underseal ,Rust prevention. Is it worth it. ?

I had mine Dinatrol'd at 2 month old and paid about what you have quoted. If you are planning on keeping long term like me, then it will be worth it. Over 10 years it works out at £85 a year which is not a lot. The place i used local to me also does a free annual inspection and touch up if you have managed to scrape some off. Or had replacement parts. If it delays and rust related by 5 to 10 years then I'll be glad I did it. Only time will tell.

It might be a bit extreme but a body off Raptor respray on the underbody would be around £1000....... If I were considering keeping one and with the way prices might go in the future, it might not be so extreme......

Lanoguard, Moto kit for 65 quid, DIY, last ages!

Did mine myself using body shuts, but ofc I have a lift, air compressor and the spray gun for it. Cost around $60usd for product. A lot of elbow grease to get rid of old rust

I'm guessing that's Rochdale Rust Proofing, they quoted me the same price on a Jimny before, I nearly left the place laughing.

I ended up getting it done in a place in Dudley using Krown.

It's a grease/wax that doesn't dry as opposed to a waxol type stuff which kinda fills me full of concerns; I'm afraid of it drying out and rust forming behind it, hidden away and not in sight. In my head, a grease type protection won't dry out and be vulnerable to this form of corrosion.

I paid £240 or so for it. Which seemed good value compared to Dinotrol

I did Dreadnaught on the day of delivery fresh from the dealership. Now 10 years later with annual top ups she is like a 1 year old unprotected version. Vets clean but with just a few little marks that have needed additional intervention.
