I have never painted a car , nor done interior work, but I decided the only way I was going to afford to paint my car and redo the interior was to learn fast.
It took me 10 months and I really enjoyed doing it. Certainly you can pick it is not a professional job, but I am more than happy plus satisfied I did all the work myself.
My car is no show car and was never intended to be - just a cruiser than still turns heads at every outing.
My paint job and interior cost me about $2000 all up - paint, consumables, new seat upholstery, roof lining, carpet etc. I was lucky the body was pretty good. Straight and very little rust.
I also did some mechanical work - new power steering pump, new carby , new dizzy converting to electronic ignition - they were easy compared to the paint and interior.
Give it a go !
Cheers,
Frank.
