Hello
I have a 1990 Miata. Does anyone have info on the following:
1/Cracked plastic rear window--Large vertical crack. How can this be fixed 
and what company can do it?
2/Repair maintenance shop (other than dealer). I'd like to find a good shop
 in this area that is is as good as/better than a dealer but cheaper and honest (by default I go to Brown's Alexandria). I'm already aware of PBC (sp?) in Chantilly. Had a clutch done there awhile ago. Not so sure of quality since experienced guy left. I live in Mt Vernon but will go
 wherever within DC area and suburbs.
3.Detailer. Good one? Reasonable.
4. Vinyl/plastic piece on dashboard (don't know what to call it). This is the piece that surrounds the AC/heat, radio, old cassette, hazard button, etc. This has plastic corner broken off. Best way to handle this in terms of getting the whole component? Note: a guy took the broken piece and lost it: I had hoped to glue it.
5. Chemical (detergent, etc.) stain on my black fabric seat? Any hope 
for remedy?
6. Sun visors. I know most people don't like them but I would really like a
 set.(black) I feel ridiculous and annoyed putting my hand up to block the sun.
Any help appreciated.
Regards. Diane (love my Miata)
