Paint process

[jackjosh]

I am looking for some advice on the best way to safeguard my car for many years to come. It is a Porsche 944 that is undergoing a restoration of sorts, I have already posted some pictures in a thread in the projects section of some patching and welding I have done on one of the wings (other one next). I would like to know what to do what is the best paint process to follow, to preserve the bare metal for now but ultimately for it to get a bare metal respray. I know someone who could trailer my car to a paint shop about two hours away but I want to do all of the prep up to it going away for the final spray. The engine and running gear will be coming off and I want to remove and replace the under-seal also, although I know this will be a task and a half
So to recap,how do i best preserve my reworked bits for now and what is the best methods and materials to take it back to the metal and then to fully undersealed and primed ready for painting.
I have a decent compressor and a few air tools and the car is in a garage where I have plenty of room to move all around it. I quite fancy one of those rollover jigs if they are as good as they are cracked up to be.
I know it is a meaty question but any help would be much appreciated.

Here's an easy answer, media blast and epoxy prime, then filler work where needed, then re epoxy prime, hi build, Gravitex underneath and then 2k topcoat, will last for years !!!

As Langy says...

My thread might be of help: http://www.mig-welding.co.uk/forum/showthread.php?t=41582

I used Jotamsatic 80, gravitex anti-stonechip and then Jotun Hardtop AS for underneath my old estate, but there are other brands as well. The epoxy mastic primers bond well, pretty good at keeping moisture out and are pretty tough. Downside is if you leave them to fully cure then they are pretty hard work to sand but if you are going to take a while to do the bodywork then an epoxy mastic primer will keep the repaired areas rust free. A weld through primer will keep things rust free for a few months at least and is easy to remove. I'm only a novice at this spray painting lark but I found the Jotamastic 80 easy to spray and the finish was better than I thought I'd get.

I would highly recommend getting a car roller for underneath as it makes it so much easier and quicker. I have the autovip 1700: http://www.cjautosheywood.co.uk/autovip.shtml If you've stripped the car a rotisserie type is probably all you need but if not then the autovip 1700 might be the better way to go. Painting around the axle with my roller is a bit more fiddly than I imagine it would be with a rotisserie type.

Top thread, I always said to the wife we will need another Estate car once the 9-5 has had it
Thanks for the advice, it has cleared things up and that look under the Amazon is what I am after but in red.
I just have to remove that "spawn of the devil stuff from underneath", don't think there is an easy way for this though
A rotisserie type is what I have been eying actually, I will just tell the wife it is a hammock for summer

My Electroplating kit has just arrived I will tell her that is a homebrew kit lol

If it's old it will chip off easily enough with a good quality wood chisel, if on thick and still soft I soak it with petrol and scrape it off with a wood chisel. But agree it's a horrible job. Much easier with the car on it's side though...
