DIY spraying inside of car - Tell me know

[GrahamS]

As part of my new track car build I'm planning to spray the inside of my car. I did it with a brush last time and vowed to never do it again. Whilst I've done body work in the past it's always been with other peoples equipment instead of my own so this will be a first. I don't want to spend much and want to paint the interior in gloss black/dark grey. The compressor I've got is up to the job and I'll be getting a Erbauer ERN643ATL which should be up to the job.

My questions are as follows

Do I need primer?
What's the best paint to use? 2k?
How much time should I leave between coats as I will of course not be baking the car like you would in a proper paint booth.

Tips tips tips!
Thanks

@1985michael182 is the guy for painting.

I did the inside of my car. Used 2k paint. It wasn't the worst job. I did prime first. I have tried to paint with rattle cans before, but it wasn't as durable as 2k.

My main advice would be to avoid white. It looks nice when you first do it, but it's a pain in the arse because it shows every mark.

Ok so you said you brush painted the first time? Did you key the origional paint before brush painting the colour you applied. Also what type of paint did you use. 2k will reach with certain paints.

If you keyed the origional paint I would get a cheap orbital sander with some 400grit discs and take the top off the paint anywhere the sander will reach, saves hours and you will keep your finger tips intact. Then finish off the harder to reach areas by hand and scotch brite.
Use panel wipe and lint free cloth to clean the area to with in an inch of its life.
Mask up or remove anything/where you dont want to paint.
Then mix your paint and start painting with the roof working your way down as the over spray will land at the bottom making it dry and rough but as you paint the floor it will disappear.
If you start at the bottom and work up it will leave dry over spray on your fresh shiney paintwork.

My own personal best tip would be to get some matting agent and finish anywhere front of the driver in matt at head height to stop the shine from the sun

Good suggestion. I did the A-pillars and front few inches of the roof satin black in mine.

That's what I want to hear! Did you clear coat over the top of the base, how long between your coats and how many coats?

Learnt from my current white one! Won't be doing that again. Looked amazing when I did it. Awful to live with.

 

[massiveCoRbyn]

It does look so good in white, but it just doesn't stay that way. I didn't clear coat when I did mine, but it can help. Old works Fords were lacquered under the bonnet because it helped prevent staining.

I think I left about half an hour between coats. I only did two.

 

[1985michael182]

Why do you need clear coat? get a solid 2k paint

Thanks for the reply. Previous one I did with hammerite, took forever! I did something very similar to the prep you list last time, just didn't spray it. Looking to speed up the process this time. No specific need for clear, would just like to have it looking good.

 

[massiveCoRbyn]

I wouldn't use hammerite for anything to be honest, it's crap lol

Seems to last quite well under the car and in the arches!

I use the smooth silver on brake calipers 😂

I'll give you that, it's ok on cast brake calipers.

I wouldn't use it for anything else though I don't think. VHT aerosols are pretty good for painting odd mechanical bits, though powder coat is the ultimate.

 

[GrahamS]

Hammerite is awesome. Use it loads on the undercarriage and it takes tons of salty abuse before going bad.

 

[bloke]

rustoleum hard hat for aerosols. plus just about anything eastwood and por do is good as well. only vht i ever use is the wrinkle finish. tried their calliper paint once and would of been better i i would of drank some paint and pissed it on!!!!!!!!

I’m in the same situation here and looking to paint the inside of my car that I just stripped.

I’ve got a compressor and a cheap suction spray gun. I’ve rattle canned a few things previously but never sprayed with a compressor.

I’m struggling to work out what I’m looking for. Not looking for a body shop quality finish, just wanting something to tidy up the inside of a track car!

Cars B76 flame red and I’ve been looking about online but I don’t know what I’m ordering or where I should be ordering from.

All I’ve managed to work out is that I want to use 2k paint for best longevity. 2K doesn’t need a lacquer, but does it need primered or just the surface key’d and well cleaned?

If anyone can send a link to what I need to order that would be brilliant!!

 

[1985michael182]

Key the surface with red scotch brite.

Any bits of surface rust remove with some 180grit sand paper

Remove any brackets and bits of metal that are no longer used " weight reduction coz race car" for free power to weight ratio mod.

Panel wipe everywhere with lint free cloth and use a blow gun to blow any bits off your areas. Could even use tack rags but its s bit over kill for the interior.

Use an aerosol etch primer (upol do a good one) on any bare metal.

Then for ease of use and not to complicate things for you use an aerosol high build primer on everything you are going to paint your top coat with. The idea is to make everything one uniformed colour so the top coat covers everything equally and you dont get patchy paint work.

Let that flash off for 15/20minutes and then hit it straight away with you 2k top coat. If you leave it too long the top coat wont stick, if you are too early it will react with the aerosol.

Your 2k comprises the colour itself and an activator which you will need to mix in the correct ratio for the paint brand you choose. Need paint thinner to clean your gun out afterwards aswell.

Easy

Standox Standofleet 2k is good covering

Painting the inside of a track car (a car with no opening windows or air con!) black, will be a regrettable decision in the peak of summer when you’re waiting in the pit lane to go out.
Trust me! 😂

 

[1985michael182]

That's part and parcel of it being a track car though

 

[massiveCoRbyn]

It's hard to choose a colour really. White is a ball ache, as it shows every mark.

 

[1985michael182]

Metallic grey always looks classy

 

[Eddie555]

How long it lasts will be another story.. All i did was Scotch Brite everything and panel wiped it then blasted 6 big cans off Mondial over and 6 big cans of Clear coat.. I ran out of blue and just did the rear floor gloss black.. End result looks fine, not perfect but its a trackcar and i needed something to do whilst bored.. Before and After..

 

[JezzaMac]

[mention]1985michael182 [/mention] is it just one coat of colour?

Would 1L of colour be enough to do interior including roof?

 

[1985michael182]

2 full coats usually. You will need more than 1L and remember you add hardner so you are diluting the paint creating more litres. Cant remember mixing ratio think it's either 2:1 or 3:1

This is a perfect example of why you need to prime first. One unified colour for your colour coat to lay on top off.

I'd agree with you as you can tell the paint is patchy in places, like under the seats.. TBH it probably needed a few more coats of basecoat but i wasnt able to get anymore.. But i would also say it doesn’t look as bad as the pictures in real life..And as i have already said its a trackcar and i just wanted it to look a bit tidier plus it helped use up 6 days of lockdown boredom..

I didn't end up spraying in inside and ended up using hammerite but I have recently done the engine bay using 2k. I would never do it again without a proper airfed mask. The stuff is very nasty so if you decide to do this make sure you have the proper equipment to protect yourself.

2k engine bay bit orange peely, primed with Bilthamber eletrox

Hammerite interior

 

[1985michael182]

At a minimum you need a 3m paint mask. Cover your hair as it dosnt like coming back off. Gloves.
Top tip if you get over spray on your upper face and eye rows use vaseline it comes straight off 👍.
In a professional placement though defo need airfed mask.

 

[1985michael182]

Like you say they are track cars not show and shine, yea we all want them looking right but mechanical is really where it's at

I painted the inside of my PH1 in the middle of winter on a pitch black night. The amount of overspray on the windows gave it a frosted glass look
