Yeah, this is part of my confusion, whats the acid etch primer for? Just put the Wurth on bare metal then there's got nothing for the water to get under.Acid etch primer on bare metal for sure. I am putting some Wurth underseal body coating on my 944 with a gun and compressor as per the factory finish and it'll be good for another 30 years. Just make sure it doesn't get chipped anywhere as when it does and the water gets in, it will then peel off. So an annual check underneath is worth it. I've thought I may get some bedliner to redo the 240 underneath.
Bilt Hamber have some good stuff as well.
Yep, what's the point of the primer, just fire on the Wurth?You can put acid etch primer on but you can't leave it at that - it's just a primer. It's meant to have a topcoat of something. It's microns thick whereas the Wirth will be 1-2mm thick.
Maybe it does, cause if it chips the water gets underneath it and the Wurth just seals in the water. Not trying to be a smartarse here, genuinely trying to find out whats best. Recently, 3 years ago ish drove my daughters Fiat 500 off the ramps and crushed the sills broke the paint and promised I'd paint it , I didn't, it's still not rusted? Also recently removed underseal from the sills of a 70s Datsun and they were like new.To stop it rusting while I'm getting the Wurth ready! It doesn't hurt to put it on.
Were those sills galvanised? Anything between moisture and metal is better than nothing.
POR15 is useless on bare metal as it is for Painting Over Rust as the name suggests ...
I’ll have to defer to the paint shop on that one, my paint skill ends after priming! They told me that they mixed my colour into the Raptor so I’m guessing the Raptor is clear.I agree! I've never had much (any) success with POR15. I always think it's for people who can't fix the rust! I think there are better solutions out there. I am intrigued by this tintable raptor bedliner stuff which is supposed to be as hard as nails.
So do you buy it and mix your paint with it or buy it already mixed?
A combination of front main oil seal, oil pump leak, sump gasket weep keep the front rails in great condition. The gearbox generally leaking from both ends keep the middle area coated and the broken diff breather sorts out the rear.
