So, I've been working on some all red rear lights for a little while, as I mentioned earlier I started with some poverty spec lights which I sanded back with various grades of wet and dry paper to get rid of some imperfections in them.
I sprayed them but wasn't happy with the finish so painstakingly sanded them back down and started again. I spent a while prepping them again and then sprayed a few coats of tint spray which gave this result:

Much better! Until I stupidly thought 'I'll just give them a few coats of lacquer', what a mistake that was and this is the outcome:


The lacquer reacted with the spray and I could literally peel sections off in sheets


I then set about sanding them back again!

I got them finished again today but haven't got any final pictures yet as I'm giving them 24 hours to harden properly.
I also spent half an hour more on the rub strip, I chopped sections of a rear rubstrip and plastic welded them into the recess of the front one:


I then sanded back the welds a bit:


It's not perfect and will need some proper sanding before a skim of filler but it's a start at least!
