Cost of Materials to Spray a Car

[steveo3002]

you're in for a world of pain if you go back for another litre in 6 months and it dont match , then you end up having to paint a whole side or front end to make it match

I did 3 litres on mine and that included a bit of wastage and some interior trim, the rest was all on the outside and there was a couple of drops left in the bottom of the tin.

Thread 'Rust again !'

Nov 10, 2024

Some time ago i tried my best too erase these rust spots, but they have come back

Start to finish through the week, ground out rust spots and covered with Fertan, brushed on Lechler epoxy primer and flatted back and fill as required, several thin coats of Lechler hi build as I'm only using my 1.3 gun, quick guide coat of black etch primer from a can, flat back and feather and several coats of ie ? gloss too flat back tomorrow, match is good !

The plan is too fully strip the area with a some 50mm stripping discs, then spot blast the areas that require it...

Thank you for the advice and suggestions.

Whether I spray the car myself or pay someone to do so, the shell will be sand-blasted and etch primed prior to welding up any holes or damage. I have details of a firm who are used to blasting these cars. I have access to a workshop which is large enough to walk around the car comfortably, but I confess dust would be a concern there. At home, I would have do it panel by panel and would have to worry about cat hair as well as dust. I do like the look of hand-painted coachwork, but as I cannot even paint a garage door in gloss without runs, I suspect that a car would be "interesting". Quite quickly, paying to have it sprayed is becoming more and more appealing.

James.

epoxy primer please

as for brush painting...practice makes perfect , im guessing many of the panels can be laid out flat on a table

I'd definitely not put epoxy on it before welding works it's near impossible to weld after epoxy. To hold back rust for a bit I would use a wash etch.

I have all shells dipped now and bought back bare for metalwork repairs. Sand blasting no matter how good they say they are warps panels.

After repairs they go back for dipping and e-coating before I begin my paint process.

Try a proper oil based coachpaint, first strokes at 45degrees, then horizontal, finishing vertically. With a decent brush obviously. You will be surprised how the paint flows and the brush marks disappear.

Did a bit of spraying the other day on a car and not sure if anyone added these but...
Panel wipe (5l brake cleaner will do) £12
5-10 microfibre cloths £5
Good quality (wurth) pump up sprayer for spraying "panel wipe". Maybe £15
Chemical gloves (marigold industrial and showa are good) for cleaning out gun etc. £10
Disposable gloves for applying panel wipe, mixing paint and spraying. £5

not sure i would suggest brake cleaner over panel wipe , some can be quiet angry and may upset old paint /poor quality primers , proper panel wipe isnt any dearer and id not risk messing up a job over it

glass cleaner spray is popular with youtube painters- again i dont want to be riddled with silicones because i cheaped out

Good advice. I will often use brake cleaner for an initial clean, but always panel wipe before painting.

Fair point. When I last bought some I found brake cleaner about 50% cheaper than panel wipe but you're right it's not much more expense in the grand scheme of things. PRO XL panel wipe seems to do the job and only a few coins more than brake cleaner. Whilst I've never had any issues with residue or fisheyes with brake cleaner it can dissolve 1k primer a bit more than proper panel wipe as you say. To avoid that I usually just spray onto a microfibre cloth then wipe which isn't the officially safe method for ensuring proper decreasing. If it's cured epoxy primer I spray onto the panel then wipe off.
That glass cleaner the YouTubers use definitely makes me suspicious because it foams. Anything that foams is surely going to leave some sort of residue.

 

[steveo3002]

yeah on the scheme of things its cheap , a 5ltr can lasts me ages and if its reducing the risk of spoiling a paint job then im all for it

The only thing to use for wiping down panels is panel wipe. It says it on the tin.

Panel wipe is dirt cheap comparatively. Paint isn’t. Time isn’t. Not worth using anything else.
Likewise with thinners and gun wash.
