Napa Crossfire Acrylic Enamel respray

Post by arodnom on February 21st 2012, 5:16 pm

Hey all longtime lurker !

love the site.

I'm spraying a 1973 MGB with Napa Crossfire Acrylic Enamel (Blaze red). This car is a driver not a show car. I'm sanding the car down with 320 scuff pads. This is the first time I have ever painted anything. I do have a 6 hp 30 gal craftsman air compressor and water seperator. I had a few questions and wanted to know what you pros think.

*Should I use a conventional gun hvlp or turbine? The Turbine is a rental from Home depot and is a 4 stage.

*If I go the route of Hvlp gun should I use a tip smaller than 1.4? I've read where people use 1.0 for AE SS and turn the air up.

* I also read I don't have to use a hardener but it won't shine that well. Is a hardener necessary??

Here is the paint

Guns I'm looking at: I can spend a little more if it means a better flow less OP

http://www.harborfreight.com/high-volume-low-pressure-gravity-feed-spray-gun-66222.html

The car does not have any rust. I cut out all the bad and installed new metal. I'm using rage extreme for smoothing out the welds. I'll wash and remove wax, remove all the chrome, sand, filler. The new metal is already primed.

Any other tips will be much appreciated.

Thanks

A 1.4 tip should be fine, as far as the gun goes I use hvlp, the main thing to check with your compressor is how many cfm does it put out , you need at least 90 cfm to operate a hvlp gun properly, and of you are going to buy one from harbor freight look at the purple gun in the hvlp, it's a better gun than the one's in the kit you have posted,get the one with the regulator I've painted about 10 car's with this gun and have great result's,I also have a devilbliss and a binks' in siphon feed gun's and vaper and sata in hvlp, but that's just my 2 cents worth, martin senior is decent paint but I prefer ppg or dupont , omni is ppg's line of value priced paint's and nason is dupont's value line, have had better result's with the omni and nason,but make sure you claer coat the omni to guard against fading, if you have'nt purchased your paint yet check these line's of paint out if your on a budget,hope this help's!!!!! thumbs up

Excellect advice! I have the same "purple" gun and it shoots very well. I actually like the feel of the gun better then my $300 Sharp HVLP gun. CFM is the key with HVLP.
I would most definetly use a hardener. Spend the $, it's worth it.

Ok. I did it Smile I need some hugs man. :bighug: lol

I used the turbine from Home Depot. It's a accuspray 9100 5 stage turbine hvlp siphon fed with 1.3 tip. I have never painted before so please understand. I think it looks like ****... It was not the gun, paint, taping, temperature, airflow, lack of experience (maybe). I think it looks like crap because my prep work sucked. I thought I had sanded down the very thin coat of filler enough to hide the welds, or body work. Now the paints on I can really see the ledges around the filler.. I should have feathered it out more. I should have laid a coat or two of high fill primer and then block-sanded it. I think I have a small run on each panel lol. I know the pot dripped like 5 drops on my hood.. I spent 30 bucks on the turbine (rental) and probably 100 on paint and supplies. Its a cheap job.

Anyone know how to get rid of runs in SS AE non-metallic? Smile

you need a run blocker to cut the runs ,and a careful water sand and buff will take care of the peel and trash in the paint.

Well I went ahead and sanded off all the edges and now I'll feather out a little better this time. I'm also going with a heavier primer in hopes of sanding/block sanding those spots again. Well it was a nice paint job at least for a day for a day Smile








Thanks for all the advice

Use a good filler primer,if you get the aerosal it will say filler primer on the can, sand these spot's with 320 then put on two good coat's of primer then sand with 400 then 2 more coat's primer then dry sand the whole car with 600 and shoot some more paint!!!! thumbs up

What are you using to sand, your feathered spots look really small, never put sand paper on your car without a block or you will always see the edges.

Hey T

I used a small DA to just mark the areas (drips, sags, runs, waves, ridges) while the sun was out. I wanted to make sure I would be able to see them in the garage. I used a 6 inch da with 180 around all of those marks. I then sprayed two coats of primer Hi-Fill. I blocksanded the two coats with 320 and hit the rest of the car with 320. Now I'm spraying two more primer coats and then going to blocksand the whole car with 500. This will make sure everything is even and flat. While it sucks I'm redoing it all, it has been fun learning. No doubt in my mind I can get a great finish next Tuesday. 70% of the car looked great the last time. The paint I put on flows well, and really highlighted the areas I need to sand and work on. Here's a pic now with still some more work ahead of me Smile

Sounds like you have the idea, I did my sons car in black so my learning curve was steep, do you know about using guide coat when blocking your primer? it will really help you see the highs and lows.

There are some excellent youtube videos on block sanding and guide coat use. I may have posted a few on this forum, I can't remember. When I did the rear quarters on my Falcon I would say I had 20 hours alone in block sanding. I had a lot of welding and body word so getting the body line straight again was really difficult. But looking at it all done it was worth the time.

Some of the areas re-sanded I went all the way to bare metal. I know I have to spray a primer on it, but how much? It was like rockchips that I had to sand down. How do you handle those? The above pictures I just hit with 120 on a da. I plan next 320 with a stiff block and then 600 wet.

thanks

I would roll on some rusto primer. It's easy to roll, no spray mess and easy to sand. It will fill in most of your chips.

It would be perfect for that paint. I love the stuff. I get it at my local Auto Zone. Then I use the same in spray cans for small and hard to get areas.

wow You guys were right x2 thumbs up

Check these out, and no runs!!

Any tips on getting slight orange-peel out of Single Stage Acrylic Enamel? Does wetsanding work on a SS like it does on a BC/CC?

Oh for sure! Thats the name of the game "wetsand untill your finders bleed" LOL
If your done painting let the paint harden up for a week or so. If the OP is slight then start with 1000 grit then 1200 or 1500. If you have never wetsand then ask a lot of questions because your nice new paint job can turn to crap very quickly.
Car looks great by the way.... thumbs up
