what you think about POR-15 ? maybe wire brush, por-15 and than waxoyl ? there is quiet a lot positive and negative reviews for both of them.

Just wonder, somebody might have some experience with both products. which is better ?

Curran

Havent done the job personally - just from reading forum, Waxoyl seems to be the common product used!
Never heard of POR-15, but just googled - both wouldnt hurt!

Not very OT, but does this process not involve a LOT of work in getting the underside of the car totally clean before applying the Waxoyl?

I am planing remove most of underneath ... will start from rear side, will remove fuel tank, exhaust and all suspension , than work on rust..... with metal brush, cleaning , preparing for painting .... not bad reviews from POR-15 with waxoyl on top of it, when finish with rear side (up to catalytic converter) , will assemble everything back, and then remove front suspension , maybe front wings also, .... i have decide what to use finally, as remove things will take a lot of time and effort. .. main thing is have right paint, that i will not need do it again in nearest 4 -5 years, .. around that time i am goin keep that car.

Interested in this thread.
Having not used waxoil before ... Is it actually a paint???... I always assumed it was like a barrier cream..a thick oil that sits on the surface but eventually comes off.

I'm taking down my rear subframe aswell to do bushings and I want to give it a lick of something.
Hammerite do a rust eating gel that's supposed to be good.
Bilt hamber do a load of different products too (cleancar.ie)
I literally want to give it a quick scrub throw some rust eater on it then paint and forget.

Marty, perhaps just use a wire brush and then hammerite direct to rust paint?

Last owner did that little over a year ago(can't be sure he used much elbow grease)... But it's flaking ready.
I dint mind buying a few products.
I got a quote for shotblasting the subframe...300 quid!!
That's too much!!

A few months ago I did my calipers. They were covered in rust so I got a wire brush at them and scrubbed each one for 5 minutes, cleaned them then applied the straight to rust paint. I then applied a coat of Halford's petrol-resistant lacquer to help strengthen it and they are the same now as the day I did them.

My opinion is that the previous owner didn't scrub these parts enough to remove the majority of the flakey rust before applying the paint.

Cheers... Will look for that paint.
I want to put some rust eater type stuff on it first though.

anyone have idea, how many liters need to buy to do all cars underneath, make sure that no need run to get some extra.
and what is reasonable price for those rust treatment paint ?

thanks

Waxoyl is old news...you need to look at the Bilt Hamber stuff from Cleancar.ie the dynax is the biz;)
