Heh just wondering what to use to paint my chassis.
I have been thinking of por15 has any one used it and is it an easy project?
I only want to do small areas at a time.
Is it ok to do a small part and later come back and do more does it cover ok at joins older to new bit as i want to do under bonnet area now and later when i can get up in the air do underneath,
any help appreciated Ian

 

I sprayed my frame with epoxy (DP90LF) and then a 2 stage chassis black. I used POR15 on my car trailer and wasn't happy with the results and the aggravation of the clean up and won't use it on anything again. I also got a wand and sprayed the inside of the chassis with chassis saver black.

 

I would use the "search" button, as you will find many different thoughts on this topic. IMO, POR 15 is good, have to be carefull using it, use in a well ventilated area. I am going to do my 74 in a few months and will be using the old Krylon #1613 Semi-Flat Black for the project. Sure you can do a small part and come back and do more. But if you want an even finish, I would do the last or final coat all at one time to get the "perfect" finish you may be looking for.
Also be sure to prep the chassis, doing the obvious, remove all grease, grime and surface rust that you may have. If you do the right prep, you should be happy with your results no matter what type of paint you use..................................... ....................Tom

 

I've used Chassis Coat Black by the same maker as POR 15. It is easy to spray, bonds well, dries quickly and has an OEM look. I have also used POR 15. It is great paint but more difficult to use. It takes much longer to dry and is more difficult to spray. It is too glossy for an OEM look. However, they do make a semi gloss version of POR 15 that I have not tried.

 

Hi V20,
I think regardless of what material you choose you shouldn't underestimate how important and how much time and effort getting the frame ready to paint can be. It's a LOT of very DIRTY work!
The preparation really determines, to a great deal, what the finish paint looks like.
Maybe the actual painting time is less than 5% of the preparation time. For some people it's probably more like 1%.
What are you goals for doing this?
Regards,
Alan

 

Alan is right (as usual). The prep time will far exceed the painting time. I have used POR-15 and the main issue I had with it is that it has a tendency to run. You have to be very careful that you don't put too much paint on at one time or it will sag and run. The other thing is don't get it on any place that you don't want it to be on permanantly. That includes yourself. If you do, you can count on it being there for a couple weeks until the skin dies and it peels off with the dead skin. I would also wear goggles when using it. I can't imagine the damage it would do to your eyes. If you spray it, use only a respirator recommended for it. I can't imagine the damage it would do to your lungs either.

For my frame I first used Master Coat. It seemed to work very well and was less prone to runs and sags than POR-15.



Then I used an epoxy topcoat from the same company. It wasn't as easy to use and some of it came off my trailing arm because some brake fluid got on it.



I used POR-15 silver on the gas tank and differential and got good results but there are a couple runs that I missed. It's a good thing that I was just looking for a fun car to autocross so I wasn't as disappointed as I would have been if my goal was a show car.

 

Is it possible to paint the chassis without doing a frame off restoration?

Well...I know it's possible, but can you get the desired results.

 

Hi i have done mine frame on now and am very happy with it wasnt easy as quoted earlier lot of preparation but i new it would not be easy.

 

POR-15 is a good quality chassis paint. But the real purpose of it is to get really good paint adhesion via the conversion of surface rust while using it. If you clean off all the rust (blast, etc.), then the real benefits of using POR-15 are lost. It will still cover and protect as expected, but probably no better than any good quality paint.

Read up on the application steps for POR-15. Loose/heavy rust should be removed, but remaining surface rust is expected and desirable to get full benefits out of using it.

If you car doesn't normally see rain, road salt, etc., Rustoleum will do a good job of protecting your frame. But, for "permanent" protection, POR-15 is probably better....just much more difficult to apply.

And, yes, you can paint the frame without removing the body. There will be areas that cannot be painted using that approach; but then, those areas won't be seen by anyone, either.
