Chassis restoration

txpjl

What's the best way to restore a chassis? I figured sand blast, then double dip in hot zinc then 4-5 coats of paint etc.

Anybody got any better ideas?

Thanks in advance

By 'dipping in zinc' do you mean zinc primer or actually having it galvanised

Not sure how good paint adhesion is after galvanising, I have never known it to work out successful long term, but their may be better paints out there now

Any separate chassis vehicles I restore, I always sand blast the chassis and send it off to be powder coated black, looks great when done, very durable and long lasting, and a doddle to keep clean compared with chassis paints.

Not too expensive either

Paint it with with Hammerite, then coat it with underseal.

I really don't know. All I heard is dip in hot zinc then paint.

Txpjl,

what is the chassis off and what use will the vehicle be put to ?
To what overall standard do you propose to complete the restoration/rebuild as in showcar standard, for daily use, etc. etc.

It's a 4x4 a BJ 40 and will be a daily driver. All the body panels are bring replaced with aluminium so i won't have to worry about rust ever again. I want the same for the chassis.

Just looking for ideas for the best way to do it.

You could galvanise it and then just leave it as is. However, It can look wrong on some vehicles and personally I dont like the bare galvanise look.
If you galvanise it and intend to paint it make sure you use the correct primers and paints or else the paint will just flake off.

I would have it blasted and then apply epoxy mastic primer. I would follow that up with 2 good coats of epoxy mastic rust proofing paint. You can overpaint that with body colour paint if you wish

I would also liberally treat the chassis interior with Dinitrol cavity treatment.

Powder coat is the ultimate job, very durable finish and its easy to keep clean. Also a lot less bother than going near it with paint.

I Got a jeep chassis sand blasted and powder coated black for 170 euro. Dropped it down one morning and collected it the next. Couldn't be easier:pac:

So many people powder coat stuff on cars these days. I dont get it at all! Once the powder cracks, water just gets sucked underneath and starts to eat away the metal underneath!

Just paint the chassis !!

Bookmark this page as you might want to revisit it!

Unless you have inspected every inch of your chassis you wont know if they are 'still as good as the day the came out of the oven'. Thats the thing about powder coating, you wont know until its too late.

I used to sell the stuff !!

I got my first one done about 12 years ago and its still perfect, I even poilish up the exposed bits when doing the paintwork . I have it up on the lift every year for the service and there are no issues with any of it, and I do give the whole under side a pretty thourough inspection

I use it in all weathers too, winter and summer and off road, (its a small SJ). Other ones done more recently also fine. I can only give my experience.

Well that's just the thing. I thought with powder coating the paint was fused to the metal and could not crack? I thought it did not chip either like regular paint?
