Active silicone used but instructions say neutral - shower tray. Should I be worried?

[Question]

I had a shower tray replaced (previous one failed).  The fitter has used active 785 sealant and I think OB1 as well (between tray and  tiles/wall).  Instructions say that I should use neutral slicone and other types of sealants can damage the tray. 

 

Should I be worried? 

 

(I am so fed up with tradesmen and their shoddy work.  This tradesman is one of the better ones).

I think OB1 Adhesive is probably OK. It claims to be solvent free. 

 

There are several versions of 785. I think 785+ is an acetoxy type, 785n is Neutral. Pretty sure lots of people have used both on trays..

 

For some reason I can't post a link but there are people on the diynot.com form that say...

I have never had any problem using the non neutral cure version with acrylic trays. IIRC, you should not use neutral cure silicone with porous stone tiles though.

I believe that rather than adhesion with acrylic, the potential issue is the 785+ might discolour/etch the acrylic. I have never experienced that

I have tiled 30+ bathrooms, many of which had acrylic basins or shower trays. I haven't experienced any problems with the acetic acid versions.

 

Some people say the neutral n version sticks better.

Thanks very much.  I am getting mixed message from my research.   Neutral also seems better for wet environments.   I think my shower tray isn't acrylic.
