Thread: gal or paint?

I considered gal on my chassis too, but in the end decided paint and regular rust proofing would do the job, Mainly avoided the gal because of the possibility of warping the chassis and the work involved in preping the chassis to gal.

I had mine done a few years ago, and warping with a chassis frame really isn't an issue.

However I sort of wish in some ways I had just painted it now, although thats only becasue I keep thinking about future mods, say coil overs, and the galvanising makes it a real pain.

The galvanising is a much more durable finish, and will stop rust even if scratched through to the steel underneath.

Galvanising requires the frame to be very clean. the end result depends on the ability/laziness/mood of the operator of the hoist aswell.

If you can clean the chassis very well then IMO nothing it is better that a full paint program using POR15

Was yours done over here Pete? all the places i spoke to about it didnt really want to do it.....

Hey Cal,

No I had mine done back in the UK

Chucaro,

While POR15 may be good, Gal is much better!

As an ex steel yach builder with few under my belt I can telling you thta POR15 is well ahead of gal providing that the job is done properly

On what basis??? Steel yachts/boats aren't hot dip gal'd, so you cannot compare like vs like.

Galvanising will protect areas of bare steel up to 6 mm diameter from corrosion (if surrounded by galvanised material). I bet POR15 doesn't?

I have seen galvanised steel in regular contact with salt water last 30 years without needing any maintenance. How often do you need to reapply POR15???

Well there are a lot of galvanized parts in steel boats that get rusty after some time specially where they recieve impact from water. The rigging screws are one of them that many sailor using them because unlike the SS screws on the gal to replace them when rust is present.

Other examples are the ruddre and rudder post and I can keep going on.

The under coat of POR15 after dry you do not tremove it with a chisel and hammer and no paint bite on it. The second coat have to be apply when the paint is tacky to bite on the under coat

One application more severe than marine and vehicle chassis is the inmersed centrifugal pumps used on the sewerage ponds and on the liquid fertilizer miexers.

The gal pump bodies last about 6 months and then an overhaul have to be done.
The POR 15 painted bodies last over 4 years and when removed for general maintenance the body of the pump was OK.
If the above examples are not good enough for you then..........it is your call
