Has anyone had success only mechanical etching the upper fuse with sandpaper vs acid etching?  (When prepping for the windscreen to be faired in)



I'd really like to avoid chemically etching that area as I have lots and lots of cash sitting directly below that area in my panel and also already have the windscreen secured in place with Weld-On. 



Just collecting info before I proceed. 



Thanks,

Phil

My whole plane was sandpaper, no acid etching for me at all.

IMHO and it's only my opinion ..... if the aluminum is clean and without 

corrosion the epoxy resin will stick just fine.

However, in your situation, I would lay some 3M fineline tape where the 

windshield meets the fuse and wipe the phosphoric acid on the aluminum 

using a paper towel .... or either a lightly loaded foam brush so there 

isn't a chance of getting the acid under the windshield where you can't 

get it out.  I've always neutralized the acid with baking soda/water and 

drying with a towel.

I was thinking composite not aluminum- no sandpaper on aluminum at all.

Correction:

 I used a scotchbrite pad and vinegar to acid etch all my aluminum, than power washed area with water. In your case spray vinegar on area and scotchbrite than wipe down with wet towel, rinse and redo wipe down until it is dull and clean. Shouldn't be an issue for the hardware if done in sections.

I used an aluminum windshield fairing, instead of fiberglass. I really like it, and it turned out great. Can't remember the name of the company I bought it from.
