based on mk2 golf but could be adapted to any car
Here goes
First you need to decide where to place your tweeters
Then fix into place with a dab of fibreglass/resin
Next lay over a sheet of fibreglass matting and paint with resin, leave to dry. i also use fibreglass tissue.
Trim off excess fibreglass
Cover with bodyfiller
Next smooth down with 80 grit wet and dry to a rough shape
Add some more filler, less this time, and smooth down with 240 grit wet and dry
repeat last step but using 800 grit wet and dry, i did this twice the last time i smoothed usibg the paper WET
Now apply a mist layer of primer, leave to flash, keep applying light layers until its completely covered
your now ready to apply your colour of your choice
