I have had to do so much welding on my car, that I am rapidly heading to a full respray. The results I have got from cellulose and a spray gun have been less than fantastic. Even with a water trap, the gun can't produce a nice consistent spray and the results are rough. The colour match, Carmen Red, is also pretty poor. I know red fades, but I don't think it fades that much.
Having the traditional reaction of how much, to the cost of paint from the usual suppliers. I had ago using the cheap RAL paints on ebay. Bought some cans to try for samples. I have a panel which needs respraying I can test the paint for a match.
Ral Carmen red (3002) is too bright, almost traffic light red, Red purple (3004) is too, well, purple, but it is a pretty close match. So I am going to try (3003) next and hope that is close.
The quality of the finish I get out the can from the 1k paint is actually pretty good, almost glass like, much better than the celly. So is 1K paint an OK option for a cheap home respray or is it asking for trouble?
