As my project is nearly finished i was looking into rust proofing the underside. So... do any of you have any particular favourites? i know of epoxy mastic paint, and waxoyl but can't find any reviews!

Everything i've ever used by Bilt-Hamber i've been very pleased with. Their products always do very well in group tests too.

My car has been done with with waxoyl since it came out the factory and it's held upnvery well
When we rebuillt it it was like new in places
And not like new where waxoyl wasn't applied
So now waxoyl is applied where waslnt and the car had rusted and hopefully it'll be ok.

Is there any products to protect car bodywork?

Plan is to do some serious waxoyling with the paraffin gun soon

I 've used waxoyl, hammerite waxoyl underseal ,and Morris lubricants Ankor wax. ,not necessarily all at the same time
I think the hammerite underseal stuff can potentially be laid on too thick and when it cracks later could let water in and rust could start unseen under it so beware of that if using it.

I am impressed so far with Ankor wax , it shouldn't even need thinning as it has it's own solvent but if you leave the lid off too long or use a crap parafin gun to spray it on you might have to
It's made by Morris lubricants and i put a link to details of it on the 'Dirty D' thread in the My A series section .

I was told by a garage that works on old Citroens of all types from 2cv to DS GS and SM CX etc that Dinitrol is the top stuff ,but it's expensive .

That Bilt hamber stuff Neil put up looks interesting too.
