I am familiar with the heavy roll on goop but there are various class action law suits on that stuff

Most complaints seem to be around the stuff not adhering or just looking like crap . But if you are rolling it onto wood that is crumbling what do you expect ? I am not interested in going this route .
On paper the composites seem to be a clear winner over wood , but then you look at all the complaints about composites like hot under foot , warping in the sun , color fading , easily scratched , easily gets mold but difficult to get rid of the mold and on and on it doesn't appear to be the majic elixir the vendors would have you believe . Our deck like all others gets used , we have grills and furniture on them ( imagine that )

We have grandchildren and dogs and the more research I do the less impressed I am with composites . I may have to bite the bullet and go with wood and keep vigilant with the cleaning and restaining
