First paint job and ??? - 07/03/08 06:03 PM

I'm in the middle of the my first paint job. I am going to finish with Chromabase. Started by taking car down to bare metal then used nason etch primer followed by a couple coats of nason 2k high build primer. Found some spots that need a little filler work, then will shoot 2 or 3 more coats of high build. I plan on blocking everything down with 400 (dry).

Now the???

1. Should I sand any further...thinking of 600 (wet) or?

2. Should I use some type of sealer before chromabase, I'm using nason 421-17 (buff) high build and chromabase will be "Go Mango" orange.

3. How much paint and clear do I need to order? The car is a 1970 Dodge Challenger.

I'm also in the middle of my first paint job. I'm gonna spray 3 coats of high build primer and then block it down.I'm also not sure of what grit to block with. 320?

If you're using the nason primer, tech sheet says 400 or finer.

No paint expert but here is my experience..

1. I sanded to 400, I don't think you need to go as far as 600.

2. Before applying paint I laid down 2 thinned coats of epoxy primer as my sealer. Not sure but you may be able to order white epoxy and have it tinted? Your paint supplier can show you a generic chip and how much of a difference primer color can affect paint color. I don't think I would want to paint mango orange over gray or black..

3.Better to have to much than not enough. I know from experience. If you are painting the entire car, including engine bay, trunk, etc. 2 gallons of paint and 2 gallons of clear should do you good with some leftover for any small fixes you may need later.. Even if you do not use it all, once you start buying quarts after the fact, you may have color match problems and the costs savings is insignificant. laid the paint/clear myself (2nd car I have done), and the color I chose (which is a deeeep red/black) needed to have 4 coats of color applied to get really solid coverage, then laid down 4 coats of clear. I still neeed to wet sand and buff, but you can spray todays clears and have very minimal 'orange peel'.

Good luck!

Thanks, I am using buff primer instead of grey, Figured the orange would cover buff better than grey. And thinking wet sanding down to 600 would use less paint? Not doing engine bay, trunk or fiberglass hood. Need enough to do door jambs, underside of trunk lid & body. Think a gallon will do it?

You will still need to use a primer sealer or epoxy over the high build primer and you won't use more paint whether it is 400 or 600 as your final sand. One gallon should do it under the circumstances, but I would have an extra quart on hand just in case. I'd also rethink the use of Chromabase. It IS expensive, and for what it sounds like you are doing (not a full on resto), why not just stick with the Nason?

Final wet sand with 400 grit, seal with Dupont Velvaseal, let it haze over, then lay down the basecoat. If you're going to buff the clear later, which is recommended, cover with at least three coats of clear. I like to let the clear dry for two days, block wet sand with 2000 grit and buff. Use a hand held spray bottle with water and dawn dishwashing liquid for wet sanding, keeps the paper from sticking.

Reasoning behind using Chomabase instead of nason is because the person shooting the paint (not me) is familiar with spraying it and I have heard or read using the lower lines of paint equals more paint and not much savings?

Right now the plan is to use Chromaclear HC-7600S

Please paint that god awful car from that dreadful yellow to a beautiful orange! I know my new car is currently Yellow. I am sure it has orange primer though. Here is Ray's car looking awesome in his new color.

I haven't used that primer. I would see if there is a colored primer/sealer compatable with the chromabase as some of the chromabase colors do not have a really high solids content, and it may take extra coats of chromabase to get good coverage. I don't recall what grit was the final sanding before applying the base, maybe 600?
The base did go on really easy and dried fairly quick, but the clear was slower drying and went on thicker making it more prone to get a run.

been a while sinse I did any paint work but I have sanded more than one car. In my opinion it is easier to see when your primer is fully sanded and ready by wet sanding instead of dry sanding the final primer coat. water and a squeegee with some 400 is how my boss made us do it, but this was in the early 90's so maybe some things have changed.
