Hi I'm looking to wax the underside of my car what is the best wax and spray wax for the hard to reach places.
It's a show car and is painted underneath.
I basically want to protect it from the fear of rain going to and from shows many thanks.

 

the same wax you use on the top

 

I just use speed detailed on mine, after a trip to a show if cleans any traffic film of easily

 

A really good spray wax / quick detailer which provides much greater protection and water beading/sheeting ability than standard QDs and that you might want to check out is Britemax's #6 Spray & Shine, as it's got real carnauba wax in it. It's fine on the finishes typically under a show car and much faster than doing it the traditional way with a 'regular wax'.

I also own a concours car, painted underneath and I've owned and run detailing forums for 10 years so although I wouldn't claim to know everything, I do know a bit

 

holly shit thats nice

 

I 2nd that...ive never saw anything that clean underneath unless in a showroom and even then it's not like that....it'll be kept in a garage that goes without doubt, credit to you Colin..

 

COR! I WOULD HAPPILY EAT MY TEA OFF THAT, A CREDIT TO YOU.

 

Thanks for that I have never tried britemax just ordered one to try thanks for the heads up

 

That is car porn right there.

 

Even the garden is tidy and the trolley jack polished and carpeted

 

Wow!
Where do you start in getting the under carriage like that?? !!

 

Strip the car to a bare underside spends hours and hours spraying petrol on th remove the wax oil with a tooth brush clean powder coat and paint and polish everything, took me about 6 months doing it of an evening, not every night but hundreds of hours lol

 

Harley wax on eBay ..cheap and effective

 

Wow that looks amazing ! A credit to you....

 

Or try Fusso wax ..

 

A good quality sealant will out last your normal wax products or for the car in the picture personally with the investment and time you have put into the car I would apply Ceramics, costly but will save loads of time during the re cleaning process, I use Gtechniq products on every thing.
This is only my opinion and not trying to preach, but I look after so many show cars that have different products used, the ceramics are always much easier to keep kleen and always shine well.
