Hi Fishos,

chasing reccomendations for polish/cutting compound to bring up an older fibreglass hull.

There are places where the glass is looking a bit "milky" & discoloured, so i thought i would spend this down time bringing her back to shiny.

Any thoughts will be appreciated. The easier & cheaper the better. DIY is good for me.




Cheers & Stay safe

You really need a rotary buffer and wool pads for good results that dont take forever. I have some gear you can borrow if you want. Im NOR

 I have just found a great product called JUICE QCUT to do the first cut.

I used an orange foam pad on a dual action polisher and I was amazed at the results.

I then finished off with JUICE ENDURANCE SEALANT and a black foam pad on the dual action

I Bought the QCUT first and the guy said bring it back for a refund if I am not happy.

I went back and bought the sealant as well. it was that good

This stuff is $90 each per bottle for a litre of each but hugely worth it.

I then used the same stuff on my faded bonet of my dark blue Prado as it is an automotive cut and polish and my bonnet looked like it was repainted. 

I only used maybe 200ml  of each on a Reefrunner and it was real chalky so plenty left. 

This combination just worked and I have tried all sorts of polish and have thrown plenty of half finished crap in the bin. I also think a rotary polisher might work well 

I bought this from Premier Automotive Paints in Malaga and I have no links to them


Just hope it helps

Blitz aluminium cleaner,dilute half with water in a spray bottle( wear the appropriate safety gear) spray the oxidised area leave for 10 minutes and wash off. Then wash off again as it lingers.do small areas at a time.

Good for your trailer too .

Would not cut back if it does'nt need to be cut.
If it is just a dis coloring of the glass as in stained then I would just do a hull clean and a polish.

 Thanks very much for your advice folks. I will look into them all.

Stevo, i have a rotary buffer but thanks for the offer, i appreciate it.

Scuba, yes it will just be a clean and polish. Just like to get rid of the "milky" look from different areas.

Thanks again for you suggestions.



Cheers & Stay safe
