Urethane vs. Enamel paint...pros and cons?

[AKcharger]

Well it's that time again, car has held up well in 18 yrs since last paint but it's showing it's age and needs a "refresh" fortunately needs very little in way of body work so only concern is paint

1) Plan is PPG shopline series paint, Question is they offer Enamel and Urethane versions, what's the difference? is one better than the other??

2) There is acrylic sealers and Epoxy primer/sealer is one better than the other??

3) PPG's product flyer shows Urethane clear suitable for topping Enamel...anyone ever have a reaction?

Thanks in advance

P.S. prepare for me ranting and raving in future posts no-doubt

Agree!   Spend some time working with what you have and you will probably be shocked at the results.   Unless, you are looking for something to do... LOL

I did a light wet sand and buff on a past car that had 30 year old paint and it turned out awesome!

Putting Shopline on it would just ruin it. Shopline is only good for cheap low budget Used Car Lots. I'd highly recommend higher Quality paint on any older Musclecar. LEON.

- Leon your opinion has weight: What WOULD you suggest and back to Enamel/Urethane question. Any remarkable difference?

- Down Zero and 1970...I can see why you'd say that from the photo but there are several rust bubbles that formed and are about to "pop" so they need attention. In addition, the passenger fender has annoyed me for YEARS! It's a 73/74 and know it's wrong. I've had this fender in the rafters for years, time to get it installed

Did you want to go single stage or 2 stage base coat clear coat? Being metallic I'd go base coat clear coat & go urethane. You could maybe get away with a cheap shopline base coat if you put a high quality expensive urethane Clear Coat over it. That would protect the cheap paint some from breaking down. Shopline may look good for first year but will quickly beak down & deteriorate if exposed to the Sun. Being cheap I'm not sure if the break down is due to no UV light protection. I believe most high Quality Clears will have UV protection nowadays. You can use a single stage paint & then clear over it but that kinda defeats the purpose of using a single stage & single stage metallics are much harder to spray evenly with no zebra stripes or mottling. A car done in all shopline might be OK, If it stayed covered in garage 99% of it's time. LEON.

Looks like you do have some work to do.   Good winter project!

Thanks Sir, copy all

Just for FYI I shot PPG Omni on my last '70 in 2004, Single stage with Clear over it....it still looks good to this day. Shop line was purportedly the replacement for OMNI...so that's all I'm going with. $$ isn't an issue as much as product experience. Again appreciate the input 

- Down Zero - yeah, have some time and plan to take this one to Carlise in June so need to make it presentable

  When I started getting ready to do my 70 I asked the same questions. Here is my saga: http://www.dodgecharger.com/forum/index.php/topic,88583.0.html
While mine was a "save what is left" spray not a nice redo like you the guys here were a great help! (My kids will get to do a proper redo.)

[AKcharger]

Oh how rude! I failed to update!

OK well I've known the door needed some lovin' and repairs were beyond my capability so out sourced it to a shop, they did well :-)

[AKcharger]

The rest of it was doable, grind, patch and fill some spots here and there

[AKcharger]

Primer day!!
Now to gap doors/fenders and block sand!

[b5blue]

  We are gonna have good weather so get it on! Looking good! 

[AKcharger]

Paint complete, now wet sand and buff...then reassembly!

[AKcharger]

Are ya happy with the semi gloss? It looks super! 

[hemi-hampton]

[AKcharger]

Nope round is the standard

[AKcharger]

Are ya happy with the semi gloss? It looks super! 

I am! I think it's about as close as you're gonna get without a LOT of time and effort and MONEY

[b5blue]

NICE! 

[hemi-hampton]

Here's a unrestored original, front of hood black out don't look as round as yours? The pic of that red one you posted don't look as round as yours. LEON.
