MG TD TF 1500 - Prep small parts now for paint later

My TF is mostly apart. In my spare time (?), I'm cleaning small parts that will be painted in a few months. I want to protect them while waiting to be painted, but I don't want to strip off temporary paint before the final paint. All metal parts will eventually be sealed with epoxy before paint.

Which do you recommend ...

> Flood the cleaned surfaces with phosphoric acid metal prep (OSPHO) then rinse and leave bare?

> Coat with rattle-can self etch primer and rattle-can enamel top coat that is not the final color?

> Other suggestions?

Thanks for your help,

Lonnie, I only use the self etch on the bare metal areas that are left after sanding. I then use a primer sealer. I've found Rustoleum better than Duplicolor for my purposes. I use rattle cans for the convenience not for the price. I have a few left over parts form a TD that I restored a couple years ago in the basement that I painted as above and they are in excellent shape, no rust or deterioration of the surface. BTW I use POR 15 on the undersides of the fenders and splash pans before finial painting. I do my own painting.

Don't leave them bare. You will be cleaning them again if you do.

Leave them alone until your ready to put epoxy in them.

Depends how you store them and for how long If its a moist area, you will need to coat them. If it is dry, I just bag or wrap in bubble wrap. until I am ready to paint. Usually don't need to do much to get them ready for paint.

With our Florida humidity, if stripped bare they can flash rust in a day. Many of the rattle can primers can absorb moisture, which can lead to flaking paint or underlying rust later. Most important to make sure if another primer is used that it is compatible with the epoxy. What parts are you doing- body color parts, suspension or what? George

I have similar storage problems with sea spray rusting stuff
Usually after I've prepared something i rattle can it with cold galvo
and if later it has to be migged on no need to clean it off as it's 90+% metal and welds through fine

My story. YMMV.
Around 1986 my son and I stripped everything in sight using wire wheels. No coating.
Frame was painted. Body was not.
That was in Wisconsin. Zinc chromate + Rostolium on frame.
Moved to NJ in 88.
In 2013 or 2014. There was a VERY slight partial cost of rust on the parts.
Took them to blaster and then paint.
The blast finish was much cleaner and better than we had done.

Like William I also use cold galvanising spray. I use it often as a bare metal primer.

Thanks guys,

A previous owner sprayed an oily gooey undercoating on just about everything. Takes a while to clean it off. The painter / stripper will remove it from large pieces. I am removing it from brackets etc.

I want to keep the freshly cleaned items from rusting until I can paint them in a few months … epoxy sealer and 2K top coat.

Perhaps the easiest way is to wipe them with linseed oil and bag them until I'm ready to epoxy seal and top coat with 2K. Remove the linseed oil with mineral spirits or blast before painting.

Dave and Willy - Thanks for the tip about cold galvanizing paint.
